Thus it can be seen, the majority of enterprises still keep firm in have litre gross margin, that surveyed enterprises chain operating profit pattern comparison of health, ability to resist risks, in the open source efficiency and mining space.Third, human resources, management cost, standardization is difficult to constitute the three major challenges. According to the survey, the current chain catering industry facing the development of the main problems include human resources, operating cost, standardization difficulty is great, malign competition, industry shortage of funds and policy support and other issues.

Investigation shows, Quanjude, KFC, Dicos and other small fat sheep, most chain enterprises still maintain established open plan.The survey, in China's sustained and rapid economic development, food and beverage market continues to be active in the background, chain catering enterprises are continuously according to the external environment and oneself condition adjustment of development strategy, to realize the optimal development pattern.2、China food industry development trend analysisCatering industry in our country is developing very quickly, the national food industry turnover for 18 consecutive years to achieve two digit growth, in recent years the catering industry growth rate higher than other industries out of more than ten percentage points, industry development prospects for many enterprises and good investment institutions, can say our country is welcoming a catering industry development the gold period, but the market is complex and changeable, will change with the social environment. The catering enterprises should according to their own conditions and environmental requirements, see the catering industry's development trend, select the appropriate marketing method, can be in the fierce competition in the market success. Therefore, the dining industry development trend of the future, opportunities and challenges to undertake brief analysis.China's economy in recent years of rapid development, GDP increased rapidly, is continuously driven home to consume demand growth factor. Historical data analysis indicates that, the catering industry retail sales growth in GDP and there is a strong positive correlation between, from the 5years development, catering industry growth amplitude is higher than the country's GDP growth rate, far higher than the social consumable total volume of retail sales growth rate, with the catering industry dimensions expands ceaselessly, to national economy presents increasingly significant role in driving.On 2004, the implementation of the catering industry retail sales of seven hundred and forty-eight billion six hundred million yuan, than going up year increaseone hundred and thirty-three billion yuan, grow 21.6% compared to the same period, for 14 consecutive years to achieve the fast growth of two digit, than the same period of social consumable total volume of retail sales growth rate is 8.3 percentage points higher, accounting for13.9% of the total retail sales of social consumer goods, the total retail sales of social consumer goods growth contribution rate of 21%, pulling the social consumable total volume of retail sales growth of 2.79percentage points.On 2005, Chinese catering industry retail sales of eight hundred and eighty-eight billion six hundred million yuan, a year-on-year increase of 17.7%, than going up year add one hundred and thirty-three billion six hundred million yuan, higher than the total retail sales of consumer goods increased 4.8 percentage points, accounted for the total retail sales of social consumer goods proportion to achieve 13.2%, the total retail sales of social consumer goods growth contribution rate and pulling rate is respectively 17.4% and2.3%. Achieve annual business tax forty-eight billion eight hundred million yuan, grow 17.8% compared to the same period.On 2006, Chinese food and beverage consumption annual retail sales exceeded trillion yuan to close greatly, achieve one trillion and thirty-four billion five hundred million yuan, a year-on-year increase of 16.4%, than going up year add one hundred and forty-five billion eight hundred million yuan.In 2007 the national catering business retail sales totaled one trillion and two hundred and thirty-five billion two hundred million yuan, a year-on-year increase of 19.4%, accounting for13.9% of the total retail sales of consumer goods, total retail sales of consumer goods led to an increase of 2.6 percentage points, social consumable total volume of retail sales growth contribution rate of 15.7%.2008 National Food Company retail amounts to one trillion and five hundred and five billion four hundred million yuan, grow 24.7% than 2007, for 18 consecutive years to maintain the speed of two digit. With China's per capita gross domestic product ( GDP ) of more than $2000, residents' consumption ability, consumption level, the Chinese high-end consumption proportion will increase continuously. In overseas, Chinese continue to attack cities and capture territories, in the first08 years of Chinese Olympic recipes, further moves towards the internationalization, the catering industry has been become pull move consumption, growth, expanding employment is one of the important factors.3、Consumer analysisWith China's per capita GDP rises quickly, per capita gross domestic product ( GDP ) of more than $2000, residents' consumption ability, consumption level and improve the level of Chinese dinner, high-end consumption proportion will increase continuously. But the food demand is complicated and changeable, the consumer tastes and consumption psychology, will change with the social environment. The catering enterprises should according to their own conditions and environmental requirements, see the catering market trend of development, choose appropriate marketing method, can be in the fierce competition in the market success.Chinese taste has apparent district sex, Chinese cuisine cooking in many schools.One of the most influential and representative for the society recognized: Lu, Guangdong, Fujian, Sichuan, Su, Zhe, Xiang, Hui cuisine, namely" eight big cuisines". The cuisine of the formation and its long history and unique cooking characteristics inseparable. But also by the region's natural geography, climate conditions, resource specialty, diet habit has different effect, it is precisely because of these differences, the major cuisine products with a strong regional, occupy the major share of the local. Regional differences, and cause consumers strongly different psychology, willing to try a different flavor. Therefore, cross-boundary operation is the next hot, it can make the unique flavor diet between each other, learn from each other. At present, eight big cuisines appear cross-boundary operation, integration trend.Catering enterprises in different expansion, but with the standard of income or other standard, differentiate the whole nation for several economic zones, in each economy area at the center of the city set up flagship store; to stand firm, again with the flagship store for the base, to the surrounding medium and small city expansion strategy.First, market positioning, namely the regional consumer groups will be your target customers; followed by the taste, whether they agree with your dish flavors; third is the value of the brand, whether they will be your loyal supporter.They had two common characteristics: first, products single; secondly, regional characteristics, after leaving Beijing is very difficult to find the right people taste identification.Since 2008, China has 46city GDP of average per capita is in above of 3000 dollar, the city 's per capita consumption level is relatively high, become meals industry regional development growth points.Chinese have a herd mentality and skeptical Mentality -- conformity, more and more local people have more sense of security; doubt, is to believe your own surface judgment, listen to others explanation.In order to fired the first shot, food and beverage brands in different places to open flagship store, large area, the seats, investment is high, the daily operation of the pressure is also big store. But all the catering enterprises have an import period. In the introduction period, both to business confidence, but also to give customers confidence. Once the introduction period to do good, attendance does not follow to go up, Chinese herd mentality came up: fewer people he does not go; more to people without a little less; he even doubt: This is it right? Straight camp shop? Taste and old whether same? Is it right? What's the problem? Cantonese cuisine since in the early 80 century in the popular date,20 years for all eternity, the main reason is the Pearl River Delta regional economic rapid development, pull the catering industry prosperity and revitalization; at the same time Cantonese broad odd miscellaneous materials. To adapt to the different needs of customers innovation, continuous innovation;, promote the sustainable development of Cantonese cuisine. With the development of economy of our country, the Cantonese cuisine in the beginning of 80's in last century to the end of 90's in the form of climate, gradually embarked on a major cuisine overlord position, become the metropolitan dishes faucet, leading the consumer trend, share growth. Food consumption behavior analysis.In recent years, the income level of Chinese dweller increases, the rhythm of life speeds up, renew the concept of consumption, promoting the rapid development of Chinese catering industry catering consumers has three major development trends.First is business consumption increase. Promoting the economic development of increased business activities, business entertainment activities promote the high-grade food development. Second is the replacement of consumption increase. With the development of economy, increase of resident income, more and more people choose to go to the hotel consumption instead of their own cooking, which is manifested in recent year 's hot. The third are forced to consumption increase. More and morewhite-collar workers and migrant workers migrant workers, time is close, and not their cooked, they are helpless, unable to be forced to at a restaurant, it promotes the fast food industry development.Dining choice not only pay attention to taste, the restaurant environment, atmosphere, sentiment has become a customer's selection of dining venue necessary conditions, consumers pay attention to enjoy, focus on food and beverage products and cultural integration, the Chinese food culture and cuisine culture broad and profound, long history, different regions show catering cultural differences also make food products with distinctive cultural characteristics. Consumers seeking" color, flavor and taste, shape, texture, temperature, sound, nutrition, health," at the same time, advocate culture and food, diet, eating habits of fusion. In recent years emerging needs of theme restaurants is developing rapidly, this concept into full play, whether it is the design of the restaurant decoration, functional layout, decor, and even its operating characteristics of cuisine, reflect a certain cultural theme and intension, catering to the product culture has the greatest degree of show. Seize the culture that a selling point, will enable the food products with infinite vitality.From the industry statistics, Chinese food industry market size is very large, and expanded very quickly, but China's catering company current situation, one is enterprise dimensions small, amount is much, modern level is low; industry standard system is not perfect; according to statistics, China's existing catering outlets 4000000, employees nearly 20000000 people,7000000 cook people, average every 185 people have1chef. The food market is relatively the most dispersed in a market, home does not have a large food group can occupy 1% of the market share. Can be said to the catering industry is perfectly competitive industry, industry concentration is very low, the future trend of development is the industry is spent centrally rise considerably, to be at a scale of enterprise integration. From the dining enterprise's competition and development pattern, the future of China's catering business competition will be more intense, and accompanied by more enterprises listed. However, in the restaurant industry high speed development at the same time, food raw material costs, labor costs increase, lack of management talent, the cost is difficult to control and other aspects of a problem to be highlighted increasingly, industry competition intensified, the catering industry entered the" era of meager profit", the traditional management mode, operation encounters serious challenges. Chinese catering industry has entered the industry reshuffle period, must exchange of new ideas, explore new pattern, quickly from the traditional" extensive type, fuzzy, experience management" to "intensive, process, chain scale management" in transition.The foreign-funded enterprises enjoy is the super national treatment, state-owned enterprises enjoy national treatment, private enterprises enjoy national treatment. Inthe restaurant industry, although not obvious, but also many examples. Domestic food business activities in addition to the normal tax, the cost of so many species, the lack of normative, area difference is bigger, the government management system is not perfect, bring about an enterprise to manage the various uncertain factors. With the further perfection of Chinese legal system construction, Chinese catering market will also further standardization. Catering industry competition pattern analysis show that, the future of domestic food industry competition situation of four great changes will take place in China, foreign fast food restaurants dominate the competition, brand has become the core competitiveness of food.At present, China's catering industry lack program guiding, the laws and regulations construction lag problem. In the rapid development of blind, disordered and low level of development of the phenomenon. Not applicable to the establishment of the catering industry of national laws and regulations system, the lack of strict market access rules and mandatory standards, catering enterprises standards uneven, incomprehensive contents, technical knowledge content is low, lack of national unity. The catering industry in our country is lack of unity within the profession of law enforcement, the market order is not standard, the dining environment is not health, food safety problems occur from time to time, market management and industry management can not keep up with the development needs of the situation, the market order to be standardized. However, countries to accelerate the service industry development strategy for the development of catering industry to bring the new opportunity. At present our country service industry gross is relatively small, the output value of the service industry the proportion of2007to40%, and the global service industry output value of the average specific gravity of 60% ( developed countries more than 70% ) far apart. In the seventeen Party Congress" to speed up the development of modern service industry, improve the proportion and level of service industry". The State Council" on accelerating the development of service industry opinions of the general office of the State Council" and" on accelerating the development of service industry in the implementation of policies and measures for advice", accelerating the development of the service sector has laid a good foundation for the development of catering industry policy, bring rare opportunity.4、From the" fast food" localization of Chinese catering industry development in future" Fast food" the localization process accelerated, the Chinese catering industry competition is intense with each passing day, and as a result of food production characteristics, just drop a " visual feast", its growth rate far less foreign fast food have. A food and beverage industry veterans have such fact: we Chinese dining culture history is long, can still sell but those " hamburger".Foreign fast food brand in China develops quickly because of its simple, reproducible, and its product localization and the theme restaurant strategy launched in China in the future, more be a trend which cannot be halted development trend.KFC launched the " tender cow five", but is Yum product localization strategy, and early in 2005April," Chinese fast food" as a slogan of" East Dawning" settled in Shanghai, has been demonstrated the yum brand localization strategy of whole body.In the face of such a break in in full fury "foreign fast-food invasion", Chinese food and beverage brands in this round of the contest has shown its advantage. For future development, China's catering industry will be faced with huge challenge.So to break the siege expand results will be aware of their own situation, at this stage of China's catering industry market situation ( for example of Beijing ), is basically in a complicated pattern.Then, how can the new round of competition advantage and expand results, we narrow the gap with foreign brand, we think, the brand building remains the primary task, the spoken Chinese catering industry has its own cultural characteristics, Chinese is inseparable from the" rushing water", so, Cola will not replace a cup of thick soup, Hamburg will replace traditional dumplings, and how to make such products with Chinese characteristics can yield, chain, is the next step to build brand of one of the important tasks.Catering to build the brand is the brand structure of fullness, also is in the main dining brand downstream to create a complete chain, from the business form echo, we see gladly Meizhou Dongpo work in this area has been done quite in place.Innovation changing, from becomes the system is the brand integration of the working key. Now food consumption has also entered the third stage, namely, the invisible, touched the overall consumer awareness stage, consumers in the left consumption places in mind to form the overall perception responds to what is, it reflects the restaurant brand culture, so the merchant's unique system is not only dishes, taste, service, environment, music, but the overall embodiment of comprehensive factors.Brand building is the Chinese food and beverage industry will break out of an encirclement is one of the important means, and real-time strategy and tactics are catering system it is important method, in order to" different region can create wonderful".Nowadays the world economic turmoil on China's catering industry development 's influence can not be ignored, China is still a developing country, in stimulating domestic demand under the premise, we still recommend Chinese catering industry occupied" Pyramid middle market", at the same time in the market to establish its own system, to make its own characteristics.翻译：1、中国餐饮业的发展前景分析餐饮业作为我国第三产业中一个传统服务性行业，经历了改革开放起步、数量型扩张、规模连锁发展和品牌提升战略4个阶段，取得突飞猛进的发展。

In recent years emerging needs of theme restaurants is developing rapidly, this concept into full play, whether it is the design of the restaurant decoration, functional layout, decor, and even its operating characteristics of cuisine, reflect a certain cultural theme and intension, catering to the product culture has the greatest degree of show. Seize the culture that a selling point, will enable the food products with infinite vitality.From the industry statistics, Chinese food industry market size is very large, and expanded very quickly, but China's catering company current situation, one is enterprise dimensions small, amount is much, modern level is low; industry standard system is not perfect; according to statistics, China's existing catering outlets 4000000, employees nearly 20000000 people,7000000 cook people, average every 185 people have1chef. The food market is relatively the most dispersed in a market, home does not have a large food group can occupy 1% of the market share. Can be said to the catering industry is perfectly competitive industry, industry concentration is very low, the future trend of development is the industry is spent centrally rise considerably, to be at a scale of enterprise integration. From the dining enterprise's competition and development pattern, the future of China's catering business competition will be more intense, and accompanied by more enterprises listed. However, in the restaurant industry high speed development at the same time, food raw material costs, labor costs increase, lack of management talent, the cost is difficult to control and other aspects of a problem to be highlighted increasingly, industry competition intensified, the catering industry entered the" era of meager profit", the traditional management mode, operation encounters serious challenges. Chinese catering industry has entered the industry reshuffle period, must exchange of new ideas, explore new pattern, quickly from the traditional" extensive type, fuzzy, experience management" to "intensive, process, chain scale management" in transition.The foreign-funded enterprises enjoy is the super national treatment, state-owned enterprises enjoy national treatment, private enterprises enjoy national treatment. Inthe restaurant industry, although not obvious, but also many examples. Domestic food business activities in addition to the normal tax, the cost of so many species, the lack of normative, area difference is bigger, the government management system is not perfect, bring about an enterprise to manage the various uncertain factors. With the further perfection of Chinese legal system construction, Chinese catering market will also further standardization. Catering industry competition pattern analysis show that, the future of domestic food industry competition situation of four great changes will take place in China, foreign fast food restaurants dominate the competition, brand has become the core competitiveness of food.At present, China's catering industry lack program guiding, the laws and regulations construction lag problem. In the rapid development of blind, disordered and low level of development of the phenomenon. Not applicable to the establishment of the catering industry of national laws and regulations system, the lack of strict market access rules and mandatory standards, catering enterprises standards uneven, incomprehensive contents, technical knowledge content is low, lack of national unity. The catering industry in our country is lack of unity within the profession of law enforcement, the market order is not standard, the dining environment is not health, food safety problems occur from time to time, market management and industry management can not keep up with the development needs of the situation, the market order to be standardized. However, countries to accelerate the service industry development strategy for the development of catering industry to bring the new opportunity. At present our country service industry gross is relatively small, the output value of the service industry the proportion of2007to40%, and the global service industry output value of the average specific gravity of 60% ( developed countries more than 70% ) far apart. In the seventeen Party Congress" to speed up the development of modern service industry, improve the proportion and level of service industry". The State Council" on accelerating the development of service industry opinions of the general office of the State Council" and" on accelerating the development of service industry in the implementation of policies and measures for advice", accelerating the development of the service sector has laid a good foundation for the development of catering industry policy, bring rare opportunity.4、From the" fast food" localization of Chinese catering industry development in future" Fast food" the localization process accelerated, the Chinese catering industry competition is intense with each passing day, and as a result of food production characteristics, just drop a " visual feast", its growth rate far less foreign fast food have. A food and beverage industry veterans have such fact: we Chinese dining culture history is long, can still sell but those " hamburger".Foreign fast food brand in China develops quickly because of its simple, reproducible, and its product localization and the theme restaurant strategy launched in China in the future, more be a trend which cannot be halted development trend.KFC launched the " tender cow five", but is Yum product localization strategy, and early in 2005April," Chinese fast food" as a slogan of" East Dawning" settled in Shanghai, has been demonstrated the yum brand localization strategy of whole body.In the face of such a break in in full fury "foreign fast-food invasion", Chinese food and beverage brands in this round of the contest has shown its advantage. For future development, China's catering industry will be faced with huge challenge.So to break the siege expand results will be aware of their own situation, at this stage of China's catering industry market situation ( for example of Beijing ), is basically in a complicated pattern.Then, how can the new round of competition advantage and expand results, we narrow the gap with foreign brand, we think, the brand building remains the primary task, the spoken Chinese catering industry has its own cultural characteristics, Chinese is inseparable from the" rushing water", so, Cola will not replace a cup of thick soup, Hamburg will replace traditional dumplings, and how to make such products with Chinese characteristics can yield, chain, is the next step to build brand of one of the important tasks.Catering to build the brand is the brand structure of fullness, also is in the main dining brand downstream to create a complete chain, from the business form echo, we see gladly Meizhou Dongpo work in this area has been done quite in place.Innovation changing, from becomes the system is the brand integration of the working key. Now food consumption has also entered the third stage, namely, the invisible, touched the overall consumer awareness stage, consumers in the left consumption places in mind to form the overall perception responds to what is, it reflects the restaurant brand culture, so the merchant's unique system is not only dishes, taste, service, environment, music, but the overall embodiment of comprehensive factors.Brand building is the Chinese food and beverage industry will break out of an encirclement is one of the important means, and real-time strategy and tactics are catering system it is important method, in order to" different region can create wonderful".Nowadays the world economic turmoil on China's catering industry development 's influence can not be ignored, China is still a developing country, in stimulating domestic demand under the premise, we still recommend Chinese catering industry occupied" Pyramid middle market", at the same time in the market to establish its own system, to make its own characteristics.翻译：1、中国餐饮业的发展前景分析餐饮业作为我国第三产业中一个传统服务性行业，经历了改革开放起步、数量型扩张、规模连锁发展和品牌提升战略4个阶段，取得突飞猛进的发展。

餐饮管理系统中英文对照外文翻译文献(文档含英文原文和中文翻译)外文:A Comparative Study of Web Application Design ModelsUsing the Java TechnologiesAbstract.The Servlet technology has been the most widely used technology for building scalable Web applications. In the events, there are four design models for developing Web applications using the Java technologies: Model 1, Model2, Struts, and JavaServer Faces (JSF). Model 1 employs a series of JSP pages; Model 2 adopts the Model-View-Controller pattern; Struts is a framework employing the Model 2 design model; and JSF is a new technology that supports ready-to-use components for rapid Web application development. Model 1 is not recommended for medium-sized and large applications as it introduces maintenance nightmare. This paper compares and evaluates the ease of application development and the performance of the three design models (Model 2, Struts, and JSF) by buildingthree versions of an online store application using each of the three design models, respectively.1 IntroductionToday, Web applications are the most common applications for presenting dynamic contents. There are a number of technologies for building Web applications, the most popular of which is the Servlet technology . This technology gains its popularity from its superiority over other technologies such as CGI and PHP .Servlets are cumbersome to develop, however, because sending HTML tags requires the programmer to compose them into a String object and send this object to the browser. Also, a minor change to the output requires the servlet to be recompiled. To address this issue, Sun Microsystems invented JavaServer Pages (JSP) . JSP allows HTML tags to be intertwined with Java code and each page is translated into a servlet. A JSP page is a servlet. However, compilation occurs automatically when the page is first requested. As a result, changing the output does not need recompilation. In addition, JSP enables the separation of presentation from the business logic through the use of JavaBeans and custom tag libraries. The norm now in developing Javabased Web applications is to use servlets along with JavaServer Pages.In the later development, there are a number of design models for building servlet/JSP applications: Model 1, Model 2, Struts , and JSF . Model 1 and Model 2 were first mentioned in the early specifications of JSP. Model 1 strictly uses JSP pages, with no servlets, and Model 2 uses the combination of both servlets and JSP pages. The terms of Model 1 and Model 2 have been used ever since. Model 1 is suitable for prototypes and very small applications, and Model 2 is the recommended design model for medium sized and large applications.As Model 2 gained more acceptances in the industry, an open source initiative to build the Struts Framework was initiated. Struts perfects Model 2 by providing the controller part of the Model-View-Controller of Model 2. In addition, Struts provides better page navigation management and several custom tag libraries for more rapid development. Despite its steep learning curve and the fact that it was never defined in any specification, Struts has been gaining popularity as thealternative to Model 2.JavaServer Faces is built under the Java Community Process under JSR-127.Sun Microsystems proposed this technology in the hope that JSF will be the ultimate model for building Java Web applications. The most important feature of JSF is the availability of ready-to-use components such as extensible UI components, easy page navigation, input validators, data converters and JavaBeans management.The problem facing servlet/JSP programmers are to choose the most appropriate design model. Clearly, JSF provides a better solution in regard to development time. However, some people are not sanguine to adopt this technology for fear of performance penalty due to the overhead of the JSF implementation.We build three versions of an online store application named BuyDirect using Model 2, Struts and JSF. The parameters compared are the number of lines of code, the number of classes, and the performance measurement results. We investigate which of the design models allows the most rapid development process. We evaluate the performances of the applications built upon these models. We provide some suggestions to perfect the existing design models to make development more rapid.The rest of the paper is organised as follows. Section 2 discusses the issues in Web development. Section 3 explains how the three design models address these development issues. Section 4 provides the details of the hardware and software used in these experiments. Section 5 presents the experiment results and analysis. Section 6 reviews the related work. Section 7 concludes by offering some suggestions to improve the existing design models.2 Java Web Development IssuesAll Java Web development uses the Servlet technology as the underlying technology. As such, all Java Web applications have certain issues that need to be addressed:User Interface. The user interface is what the client browser renders as HTML tags. Any server-side component used in the application must be encoded intothe corresponding HTML elements. Besides for displaying the content and data, the user interface is also responsible in receiving input from the user.●Input Validation. User input needs to be validated. There are two types of inputvalidation, server-side and client-side. As the name implies, the server-side input validation is performed on the server after the input reaches the server.Client-side input validation is done on the browser, usually by using JavaScript or other scripting languages. The advantages of using client-side input validation are prompt response and reducing the server workload. The server-side input validation should always be performed regardless the presence of client-side validation because there is no guarantee the user browser's scripting feature is being on and malicious users can easily work around client-side validation.●Model Objects. Model objects in Java-based Web applications are in the formsof JavaBeans. Model objects make up the Model part of the MVC based design model. A model object can be used to bind a component value to be used at a later stage. In addition, it can encapsulate business logic required for processing.●Page Navigation. Almost all Web applications have multiple pages that the usercan navigate from one to another. All MVC-based design models use a servlet as the Controller part. This servlet also acts as the sole entry point to the application. Which page to be displayed after the current request is determined by the value of a specified request parameter. Managing page navigation is critically important.3 Web Application Design ModelsThe Model 2 design model is based on the Model-View-Controller (MVC) design pattern. As explained by Burbeck , there are three main modules in MVC, the Controller, the View, and the Model. The Controller acts as the central entry point to the application. All user interactions go through this controller. The View contains the presentation part of the application, and the Model stores data or encapsulates business logic of the application. In the later development, the Struts Framework provides a common framework to easily build Model 2 applications.Then, the last initiative is the JavaServer Faces, which also employs the MVC design pattern.In the following sections, we discuss these three design models and explain how each design model addresses the development issues specified in the previous section.3.1 Model 2A Java Web application that is based on the Model 2 design model has one servlet(called the Controller servlet) that serves as the Controller part. All requests are first handled by this servlet, which immediately dispatches the requests to the appropriate views using RequestDispatcher objects. Views in the Model 2 design model are represented by JSP pages. To store data, a Model 2 application uses JavaBeans, which are the Model part of the application. In addition to storing data, the JavaBeans also encapsulate business logic. Each HTTP request carries an action parameter that indicates which view to dispatch this request to. The programmer must code the HTML tags for user interface in all JSP pages in the application and write input validation code. In addition, the model objects are managed by individual JSP pages.3.2 StrutsThe Struts Framework is an improvement of the Model 2 design model. It provides a default Controller servlet so that the user does not have to write and compile one. Struts alleviates the task of page navigation by allowing navigation rules to be present in its application configuration file (an XML document). Changes to the navigation rules do not require recompilation of a Java servlet class. In addition to easier page navigation, Struts provides custom tag libraries that define tags representing HTML elements. One of these tags is used for error handling and Struts is therefore capable of displaying localized error messages in support for internationalization. Struts applications use JavaBeans as their models, just like the Model 2 design model. In addition, Struts programmers have to write their own input validation code.3.3 JSFJSF also employs a controller servlet that is called FacesServlet. This servlet is the only entry point to a JSF application. JSF also uses JSP pages as its views and JavaBeans as its model objects. Unlike Model 2 and Struts, however, JSF provides ready-to-use user interface components that can be written on JSP pages. Upon an invocation of a page of a JSF application, the FacesServlet constructs a component tree that represents the JSP page being requested. Some of the components can also trigger events, making JSF event-driven. For page navigation, JSF uses an approach similar to Struts, i.e., by allowing navigation rules to be defined in an application configuration file (again, an XML document).What distinguishes a JSF application from non-JSF servlet/JSP application is that JSF applications are event-driven. The user interface of a JSF application is one or many JSP pages that host Web components such as forms and input boxes. These components are represented by JSF custom tags and can hold data. A component can be nested inside another, and it is possible to draw a tree of components. Just as in normal servlet/JSP applications, you use JavaBeans to store the data the user entered.4 Function EnvironmentThe software and hardware details for our experiments are described below.4.1 The Servlet ContainerA Java Web application runs in a servlet container, which is the engine that processes the incoming HTTP requests for the resources in the application. For this research project, we use Tomcat, an open source servlet container from the Apache Software Foundation. The version we use is 6.0.Basically, a servlet container processes a servlet by performing the following tasks:- Creating the HttpRequest Object- Creating the HttpResponse Object- Calling the service method of the Servlet interface, passing the HttpRequest and HttpResponse objects.4.2 Testing ClientsFor performance testing, we emulate multiple users using JMeter 1.9 , also from the Apache Software Foundation. JMeter allows the user to choose the number of threads to perform testing. Each thread emulates a different user. JMeter also lets us choose how many times a test will be done. To test a Web application using JMeter, you direct requests to certain IP address, context path, and port number. You can also specify request parameters to be included in each HTTP request. As the output, JMeter notifies the response time of the server in milliseconds for a test. From the response time, we derive the number of hits/seconds the server is capable of serving.4.3 HardwareWe use different computers for running the applications and for testing, so as to obtain maximum performance measurement accuracy. The computer running the application is a XP machine having the following hardware specifications: Intel Core 1GHz CPU with 1G RAM. The computer running the testing clients is a Windows 2000 machine running JMeter. The computer has the following specifications: Intel Core 1GHz CPU with 1G RAM.5 ResultsWe obtain experimental results in two categories: the ease of development and performance. The ease of development category compares the number of classes and the number of lines of code. These numbers indicate how easy it is to develop an application by following a certain design model. An application with the fewer number of classes or the number of lines of code indicates that the application is relatively easier to build. The application with the more number of classes indicates that the application takes more time to develop.The performance measurement results are obtained by comparing two operations. The Search operation is the most common operation in such an application,and the Browse operation.5.1 Ease of Application DevelopmentAs Table 1 shows, it takes the most effort to implement the Model 2 design model. Using Struts alleviates the problem a bit, and the best saving in the development comes if one uses JSF.Table 1. The number of classes and the number of lines for the applications under studyThe Model 2 design model is characterised by the presence of a Controller servlet and a number of JavaBeans classes (as the Model) and JSP pages (as the Views). The Controller servlet is responsible for page navigation rules that employ a series of if statements. Model 2 application programmers must also code for the input validation that in this research is implemented inside a number of custom tag libraries. The other classes in the Model 2 design model are custom tag library and the tag library descriptors responsible for input validation and data display. In fact, input validation takes 590 lines of code, or almost 30% of the total amount of code.In the Struts application, the Controller servlet is provided by the framework, therefore a Struts programmer saves time for not having to write one. However, he/she still needs to write page navigation rules in the Application Configuration file, which is easier than writing a servlet because the Application Configuration file can be edited using a text editor and no compilation is necessary. Input validation must still be done manually, even though the Struts Framework provides an error handling mechanism. The number of classes and the number of lines of code for input validation are almost similar to the Model 2 application. In Struts, the other classes are Action classes to which the default Controller servlet dispatches requests.In JSF input validation comes free through the availability of validatorcomponent. As a result, a JSF application developer can skip this task. In addition, page navigation takes the same course as Struts, i.e. by utilising an Application Configuration file. The other classes in JSF are a ContextListener, an ActionListener, and a Database utility class.5.2 Performance MeasurementFor each operation, we measure the server response time (in milliseconds) for 1 to 10 concurrent users. The number of users is specified by setting the number of threads in Jmeter. Each test is conducted 10 times and the average is taken. Each operation is discussed further is the following sub-sections.5.2.1 Search OperationThe Search operation whose name or description matches the keyword. There is one SQL SELECT statement performed. Figure 2 compares the three versions of applications for the Search operation.Fig. 2. The performance comparison for the Search operation For the Model 2 application, the average server response time for one user is 173 ms and for 10 users is 919 ms. For the Struts application, these numbers are 189 ms and 900 ms, respectively. For the application built using JSF, the average server response time is 210 ms for one user and 932 ms for 10 users. The increase of the response time is proportional to the increase of the number of concurrent users, which means that the server is still able to cope with the load.The Model 2 application has the least overhead, therefore the averageperformance should be better than the Struts and JSF applications. However, the Struts application performs as well as the Model 2 application. This is because the server has enough memory to load all Struts libraries required to run Struts. Also, note that page navigation rules in Struts are loaded and stored in an object called ActionMapping. Therefore, given an action request parameter, the next page of navigation is obtained through a look-up. On the other hand, the Model 2 application uses a series of if statements to find the next page of navigation, given the action request parameter.The JSF application performs slightly worse than the other applications in almost all numbers of concurrent users. This could be due to the time taken by the JSF implementation to construct a component tree for each page requested. However, the difference in server response time between JSF and other applications is not that significant.5.2.2 Browse OperationThe Browse operation,like the Search operation, there is one SQL SELECT statement performed. Figure 3 gives the test results for this operation.Fig. 3. The performance comparison for the Browse operation On average, the Model 2 application performs the best because it has the least overhead. The average server response time is 111 ms for one user and 899 ms for 10 users. The Struts application has comparable performance, with one user average server response time of 180 ms and 10 user response time of 920 ms. The JSF lacks a bit behind the two applications with these numbers being 190 and 1009ms respectively. The increase of the server response time is proportional to the increase of the number of concurrent users, which means the server is able to serve those users well. The average performance measurement results of the Browse operation are very similar to the ones for the Search operation because the database operations of both operations are also similar.6 Related WorkCompare the performance of database-based Web applications using Java servlets, PHP version 3, and Common Gateway Interface (CGI). After a series of benchmark tests that performs data retrieval from a MySQL database, find that the solution of Java servlets with persistent database connection has the best performance. PHP3 using persistent database connections performs fairly well when compared to the CGI solution,also mention the advantages of using Java servlets. According to these authors. Java servlets are an excellent choice to meet the requirement of e-commerce (such as online shopping) applications and are able to handle client requests in a highly interactive mode.Comparing PHP 4, Java servlets, and Enterprise JavaBeans. Measure the performance of these three architectures using two applications. Study reveals that PHP4 is more efficient than Java servlets, and the EJBs perform even worse than servlets. However, note that servlets, being part of the Java solution, provides the flexibility of being able to be ported to another system with a different operating system.7 ConclusionWe find that it is most rapid to build Web applications using JSF. Model 2 applications are the least rapid but give the best performance. Struts applications sit in the middle of the other two design models in both comparisons.We make some suggestions that could improve the Servlets technology in general and enhance the performance of applications based on both design models. Struts. Struts is not based on any specification and there is no documentation that discusses its internal working. Therefore, it is hard to know what have been implemented and what could be improved.●The Servlets Technology. The Servlet 2.3 Specification does not define anycaching mechanism. There is no mention of caching in the upcoming Servlet2.4 Specification either. Despite the dynamic nature of the content of a Webapplication, some contents do not change very often. For example, the categories of products that a user can browse in an online store application probably only change once in a month. If those semi-static contents must be generated from the database every time they are requested, a lot of programming resources will be wasted. Servlet programmers get around the absence of caching by writing an object that caches certain content. However, since there is no standard for caching, many programmers write the same piece of code again and again.●Model 2.The main drawback is that the page navigation rules are hard-coded inthe Controller servlet. This means any minor change to the program flow will require the Controller servlet to be re-compiled. The solution to this problem is to provide a mapper that reads the page navigation rules when the application starts. The code could be conveniently written in the init method of the Controller servlet. This method is only executed once, i.e. the first time the servlet is loaded into memory. If the properties file needs to be re-read every time it changes, the programmer can check the timestamp of the properties file for each request, and compares it with the previous read of this file. If the timestamp is more current than the previous read, the mapper can be re-constructed. This feature can be enabled and disabled by using an initial parameter in the Context object. At the development phase, this feature should be enabled. At deployment, this feature should be off. The use of the properties file to store the page navigation rules also makes it possible to avoid a series of if statements in the Controller Servlet, which can be time-consuming for every request. Instead, a HashMap can be used, with action request parameters as keys and the next JSP pages as values. The other disadvantage of this design model is the absence of standard components for input validation and user interface. However, this has been solved in JSF.●JSF. JSF provides solutions to common problems in Web development, such aspage navigation management, UI components and input validators. However, because this technology is still very young, there are not too many UIcomponents available, forcing programmers to combine JSF with non-JSF servlets/JSP pages. JSF is event-driven. JSF programmers determine the behavior of a JSF application by writing event listeners, just like those listeners in a Swing application. In JSF version 1.0, there are currently two types of events that can be triggered: ActionEvent and ValueChangedEvent. However, this is good enough to provide sufficient level of interactivity between the application and its users. Adding more types of events will definitely make JSF more appealing.References［1］．Cecchet, E., Chanda A., Elnikety S., Marguerite J., Zwaenepoel W.: Performance Comparison of Middleware Architectures for Generating Dynamic Web Content.

Hotel Management System Integration Services1.IntroductionIt is generally accepted that the role of the web services in businesses is undoubtedly important. More and more commercial software systems extend their capability and power by using web services technology. Today the e-commerce is not merely using internet to transfer business data or supporting people to interact with dynamic web page, but are fundamentally changed by web services. The World Wide Web Consortium's Xtensible Markup Language (XML) and the Xtensible Stylesheet Language (XSL) are standards defined in the interest of multi-purpose publishing and content reuse and are increasingly being deployed in the construction of web services. Since XML is looked as the canonical message format, it could tie together thousands of systems programmed by hundreds of programming languages. Any program can be mapped into web service, while any web service can also be mapped into program. In this paper, we present a next generation commercial system in hotel industry that fully integrates the hotel Front Office system, Property Management System, Customer Relationship Management System, Quality Management system, Back Office system and Central Reservations System distributed in different locations. And we found that this system greatly improves both the hotel customer and hot el officer’s experiences in the hotel business work flow. Because current technologies are quite mature, it seems no difficulty to integrate the existing system and the new coming systems (for example, web-based applications or mobile applications). However, currently in hotel industry there are few truly integrated systems used because there are so many heterogeneous systems already exist and scalability, maintenance, price, security issues then become huge to be overcome. From our study on Group Hotel Integration Reservation System (GHIRS), there are still challenges to integrate Enterprise Information System (EIS), Enterprise Information Portal system (EIP), Customer Relationship Management system (CRM) and Supply Chain Management system (SCM) together because of standardization, security and scalability problems, although GHIRS is one of few integration solutions to add or expand hotel softwaresystem in any size of hotel chains environment.We developed this system to integrate the business flow of hotel management by using web services and software integration technologies. In this paper, firstly we describe a scenario of hotel reservation and discuss the interaction between GHIRS and human. Secondly we analyze details of design and implementation of this system. The result and implications of the studies on the development of GHIRS are shown in the later part. Finally we discuss some problems still need to be improved and possible future directions of development.2. Hotel Reservation: A Business Case StudyOur initial thinking to develop GHIRS is to minimize the human interaction with the system. Since GHIRS is flexible and automated, it offers clear benefits for both hotel customers and hotel staff, especially for group hotel customers and group hotel companies. Group hotel companies usually have lots of hotels, restaurants, resorts, theme parks or casinos in different locations. For example, Shangri-La group has hundreds of hotels in different countries all over the world. These groups have certain customers who prefer to consume in hotels belong to the same group because they are membership of the group and can have individual services.The first step of a scenario of hotel reservation is that the consumer plans and looks for a hotel according the location, price or whatever his criteria and then decides the hotel. Then he makes a reservation by telephone, fax, internet, or mail, or just through his travel agent. When hotel staff receives the request, they first look if they can provide available services. If there is enough resource in the hotel, they prepare the room, catering and transportation for the request and send back acknowledgement. At last the guest arrives and checks in. The business flow is quite simple; however, to accomplish all these tasks is burdensome for both the consumer side and the hotel side without an efficient and integrated hotel management system.Telephone may be a good way to make a reservation because it is beyond the limit of time and space. Guests can call hotels at any time and any place. However, itcosts much when the hotel is far away from the city where guest lives; especially the hotel locates in a different country. Moreover, if there is a group of four or five people to make reservation together, it would take a long time for hotel staff to record all the information they need. Making reservation by travel agent saves consumers’ time and cost, but there is still millions of work for agent to do. They gather the requirements from consumers, then distribute to proper destination hotels. Because these hotels don’t use a same system (these thousands of hotels may use hun dreds of management systems), someone, agent or hotel staff, must face the problem how to handle information from different sources with different hotel management systems to different destinations.Web service becomes the tool to solve these problems. Our web services integrate the web server and hotel management system together, and everyone gets benefit. Booking a room easily anywhere and anytime becomes possible by using GHIRS. Consumer browses websites and finds hotel using his PC, PDA or mobile phone (WAP supported), after his identity is accepted, he can book a reservation. Two minutes later he can get the acknowledgement from the hotel by mobile phone text message or multimedia message, or email sent to his email account or just acknowledgement on the dynamic web page, if he hasn’t leave the website. The response time may take a little longer because when the hotel receives the quest, in some circumstance, hotel staff should check if there is clean and vacant room left. The web service is a standard interface that all travel agents can handle, gather and distribute the reservation information easily through internet. When the reservation request is acknowledged, hotel staff prepares the room, catering, and transportation for guests. Since the information already stored in the database, every part in the hotel chains can share it and work together properly. For example, staff in front office and housekeeping department can prepare room for guests according to the data, staff in back office can stock material for catering purpose and hotel manager can check business report in Enterprise Information Portal integrated with GHIRS by his browser. Then room rent-ratio reports, room status reports, daily income reports and other real time business reports are generated. Managers of the group can access anyreport of any hotel by the system. In the later part of this paper, we will show how consumers, agents, and hotel staff can efficiently work together by GHIRS.GHIRS is scalable for small-to-large hotel chains and management companies, especially good for hotel group. It truly soars with seamless connectivity to global distribution systems thereby offering worldwide reservation access. It also delivers real-time, on line reservations via the Internet.3. Integration of Hotel Management System3.1 Existed SystemGHIRS is developed on the base of an existed hotel management system called FoxhisTM. FoxhisTM shares the largest part of software market in hotel industry in China. FoxhisTM version 5 has distributed Client/Server architecture that the server runs SCO-UNIX and client runs Microsoft Windows and it use Sybase database on UNIX. The system includes Front Office system, Property Management system, Quality Management system, Human Resource Management system, Enterprise Information Portal system (EIP), Customer Relationship Management system (CRM) and Supply Chain Management system (SCM).This system is largely based on intranet environment. Most of the work is done in a single hotel by the hotel staff. It’s no customer self-service. If a consumer wants to book a room, hotel staff in local hotel must help the guest to record his request, although FoxhisTM system already done lots of automatic job.When the systems are deployed in different hotels that are parts of a group, sharing data becomes a problem. Just as an example, if the group has ten hotels, there would be at least ten local databases to store the consumers’ data. Because hotels need real time respond of the system, so these ten hotels can’t deploy a central database that does not locate in the same local network. Thus one guest may have different records in different hotels and the information cannot be shared. By web services as an interface, these data can be exchanged easily.3.2 DesignRecall that our initial thinking to deploy GHIRS is to save hotel staff, travel agents and consumers’ labor work the system is to link all the taches of hotel business chains. Figure1 shows how consumers, agents, hotel staff cooperate together efficiently with the system.Consumers could be divided into two categories. One is member of hotel group, who holds different classes of memberships and gains benefits like discount or special offers. These consumers usually contribute a large part of the hotel’s profit then are looked as VIP. The hotel keeps their profiles, preferences and membership account status. The other category is common guest. All these two kinds of guests and travel agents who may trade with many other hotels face the web-based interface that let them to make a reservation. For common guest, the system just requires him to input reservation information such as guest name, contact information, arrival and departure the system. The central processing server then distributes the information to appropriate hotel. Since web services technology is so good for submitting documents to long running business process flows, hotel staff could easily handle this data in and out of database management system and application server. As the membership of hotel, a user just inputs his member id and password, room information, arrival and departure date, then finish the request. Because hotels keep members’ profile, and systems exchange profile across all hotels of the group by web services, hotel staff in different hotels could know the guest’s individual re quirement and provide better services.The agents work for consumers get benefits from GHIRS as well. They may also keep the consumers’ profile and the web services interface is open to them, it is easy to bridge their system to hotel management system. Before GHIRS is deployed, the agents should separate and process the reservation data and distribute them to different hotels, which is an onerous job. But now the agents could just press one button and all the hotel reservation is sent to destination.Hotel staff receives all request from different sources. Some policies are appliedto response the request. For example, some very important guest’s request is passed automatically without confirmation, the guest could get acknowledgement in very short time. The request triggers all chains of the hotel business flow and all the preparation work is done before his arrival. But for the common customer, hotel staff would check on the anticipate date if there is vacant and clean rooms available. Because all the FoxhisTM components are integrated together, staff users needn’t change computer interface to check he room status. If it is a valid request with enough guests’ information and there is enough room left, a confirmation is sent back. If there is not enough vacant room, hotel staff will ask if guest would like to wait a time or transfer to other hotels in the hotel group or alliance hotels. In order to transfer guest’s request, data flows from local database to the central server through local web server, then it is passed to another hotels database by web services interface.3.3 ImplementationToday there are lots of platforms that could provide capabilities to integrate different system and offer other features such as security and work load balancing. The two main commercial products are Java2 Enterprise Edition (J2EE) and . They offer pretty much the same laundry of list of features, albeit in different ways. We choose .NET platform as our programming environment, however, here we don’t advo cate which platform is better or not. Our target is to integrate these decentralized and distributed systems together. In fact, both of these platforms support XML and SOAP to accomplish our task.We use Microsoft Internet Information Services (IIS) as web server and Sybase database server. The firewalls separate the local networks from the public networks. This is very important from the security point of view. Each hotel of the group has a database server, an application server and a web server to deploy this multi-tier system that includes the user interface presentation tier, business presentation tier, business logical tier, and the data access tier. C# is adopted as the programming language for the core executable part. XML is the data exchange standard format.酒店管理系统集成服务1.简介人们普遍认为，网络服务角色在企业中无疑是重要的。

酒店管理外文翻译
原文In today's world competition is the talent competition, high-quality human capital is the hotel industry continued to be healthy and stable development of the fundamental guarantee. With the hotel employees in the quality of ideas and sense ofself-development and growing the concept of democracy, the hotel that thepeople-oriented service sector in terms of human resource management staff revealed low awareness of service with low staff turnover rate increased the title and so on. This paper analyzes the status quo, therefore, material incentives, moral incentives, as well as the incentive system and a combination of four-star hotel human resources management of the actual situation of the modern hotel management incentive mechanism has done a preliminary study. In addition, some hotels in human capital development to improve the human capital level of the hotel's strategy and measures.Chapter 1 Analysis of the hotel industryHotel industry, in the final analysis is the talent competition. Management of the core issue is the question. In hotel management in the use of human resources management to obtain a competitive advantage more and more cases.Case: newspapers and magazines continue to publish articles reporting the adverse conditions of the service sector, front-line staff error continuously, the attitude of the poor is ignored customers home. Lack of skilled staff, in the face of the high rate of loss of the services sector is suffering to those who come into contact with customers to inject new vitality enterprises. Analysis showed that: when a person was a high degree of motivation, he will take the initiative to work hard to provide the customers with the best possible service; and have not been inspired, he will save energy as much as possible. The primary task of modern managers is to kindle the enthusiasm of staff working inside the fire, to drive the staff work to show the outstanding organizations in order to achieve the best performance expectations. In the enterprise has been an excellent leader in recognition of this point, only the "people-oriented" corporate governance can be in today's fierce competition for survival, development, and prosperity. Management is an art, staff motivation is the art of art, the soul of the enterprise employees. Staff to design effective incentive mechanism to increase the enthusiasm of the staff. So that it can be in various different corporate culture and organizational structure of the enterprise environment to play their maximum potential in order to achieve the expectations of the target organizations. Let us first of all, let me incentive divided into three categories: material incentives, moral incentives and the design of incentive mechanisms, through these three types of analysis and understanding, so that we understand the role of incentive mechanism and significance of the enterprise so as to establish an effective incentive system. We are encouraged by the following methods to fall into two categories: material and spiritual encouragement and incentives; incentives of thesemethods of understanding and knowledge in order to let us realize that the role of incentives.Chapter 2 material incentivesMaterial incentives is the way to the adoption of incentives to encourage trade union work.Its main manifestations of positive incentives, such as wages, bonuses, allowances, benefits, etc.; negative incentives such as fines. Material needs is the first of human needs, is engaged in social activities of all the basic motive, therefore, the material incentives to encourage the main mode is the internal use of Chinese enterprises are very common mode of an incentive.Excitation method is 2.1Hotel reward is the good organization of the behavior of employees or work performance and in recognition of the positive. Incentives as a means of staff motivation, incentives designed to induce employees by their exemplary acts to maintain and carry forward and set an example for all staff, for staff morale Fen play a positive role in promoting. Make good use of this means we must pay attention to the following: (a) awards to be timely, and an incentive to innovation. (B) the attention of other employees of the psychological. Constantly set new goals, to play down the past focus on the future, to establish a correct view of the fair. (C). Emphasis on incentive groups, activities in a modern hotel in the achievement of organizational goals, personal dignity and achievements, both need to go through the joint efforts of groups can be achieved, the emphasis on incentive groups, is conducive to the formation of a unified staff the ideological understanding, and enhance the cohesion of staff to enhance their competitiveness.2.2 negative excitation methodPunishment is a negative incentive is a modern hotel staff in order to correct the bad behavior, and to obtain a compulsory measure. Applied correctly, can be made to the wrong acts of a very good deterrent. However, employees must not be punished mainly as a supplementary means only, otherwise it will backfire. In the use of the means to pay attention to the following points: (a) those that can not teach and to punish. Give education top priority should be on the incorrigible or those who have serious consequences for the implementation of punishment, and punishment can not be hosted attention. (B) select a reasonable and effective punishment, and the scope can not be too large, but not a total negation of the attention to small or large, the psychological harm to employees. (C) will be a matter of principle to the combination of flexibility and principles, adhered to more stringent enforcement. In strictaccordance with the provisions of the system under the premise of a certain degree of flexibility is absolutely necessary, so in a reasonable incentive to be strict, strict fair, a large number so as to achieve the purpose of education, although, material incentives is not a panacea, but we have to reasonable use of material incentives that adouble-edged sword. For example: in the Jeju Island Group has a management program such that when the staff came to the company the first day of work, the company will staff the case of some families, such as economic conditions in a multifaceted understanding of the understanding on the establishment of a staff personal data, in the day-to-day work of the staff analysis of data, work in the future, managers will be on the previous analysis of the implementation of effective employee incentive program. Comprehensive understanding of the needs of employees and the quality of work is good or bad, according to the situation of constant incentive to develop accurate, thereby mobilizing the hotel staff to achieve each and every performance should be.Inspire the spirit of Chapter 3Management experts point out that Pitt had "side-effects will be rewarded, because of the high prize money would blockade the news to each other and affect the normal development, the social atmosphere will be errors." Enterprise alone, therefore the material may not be able to play the role of incentives, so they have another incentive - the spirit of encouragement. On this incentive, I roughly divided into the following categories: goals motivation and participation in competitive incentives and other incentives.译文：当今世界竞争是人才的竞争，高素质的人力资本是酒店业得以健康持续稳定发展的根本保证。

（本科毕业外文文献翻译学生姓名：X X X学院：信息工程学院系别：计算机系专业：软件工程班级：软件06指导教师：X X X讲师二○一○年六月To connect SQL Server databaseFirst we introduce the basic knowledge of the database, be regarded as the warm-up exercise that study database weave distance front!1.warm-up exerciseNeeding first avowal is relation database that database knowledge that we here introduce all point. The so-called relation database is to mean data as that the form gather, passing to establish simple form an a kind of database for of relation to defining construction.I ignore the watch at how saving way in physics in the document in database is, it can see to make an a line for with row, with electronics form is similar with the row. In relation database, the line were called the record, but the row then is called word segment.This form inside each an all in formations for is a record, it including particular customer, but each record then included the same type with the word segment of the quantity: Customer's number, name etc.Form is logic set that a kind of related information that press a line of arranging with row, similar in single form in work.Each row of the word a database form inside calls a word segment. Watch is from every kind of word a definition of its containment of, each word a data for describing its implying. While creating to set up a database, the beard assign for each word segment a the piece belongs to the sex with the other according to the type, biggest length. The word segment can include every kind of word sign, arithmetic figure even sketch.An information of relevant customer deposits in the line of the form, is called record. By any large, arbitrarily two records for database form to create set up can't be same.Key be a certain word segment( or several words segment) of the form inside, it() for fast inspect but drive index. The key can be unique, and also can then the right and wrong is unique, being decided by it() whether admission repetition. Unique key can specify for main key, using each one that come to unique marking form.The norm turns the database design of mission be method that the data of buildup, but the data of buildup, should can dissolve otiose repetition, and for have the necessary information offering to check to seek the path quickly. For attaining this kind of target but separate information to the process gone to in every kind of independent form, be called the norm turn.It is complicated process to use many appointed rules to proceed the norm with the type of the different Class that norm turn. That process studies and discuss already beyond the reach of textual scope. But, the norm of the simple database in majority turn and can use the simple experience in underneath rule completes: include the form of the information of repetition must be divided into independent a few forms dissolve repetition.If we have chosen to learn 12 curricular 1000 students, the each curricular elucidation will show with the teacher 100 many- to choose that curricular and eachstudent repeat once. To avoid this kind of low efficiency, should to turn the dichotomous and independent form in form to the norm,an is used to mean the student, the another uses mean the course.Now the form was turned by the norm, so, to changes the particular and curricular course describe or" data", as long as change a record all right.Is a basic knowledge concerning database above, this is what study database plait distance must. Although the database technique is used as a course, its depth is not this space and can describe with the wide degree of, be used as the primer with simple database plait the distance should be all right already.Like, underneath we can start practicing. We usually meet the database system is to registers the system, ignoring you are in the unit, or attend what buildup, the register is to cans not help of, and it of the construction is more simple, we take a register system as an example. The analysis is once a data for involving.2. understanding the elementsFor the register, want the on the trail of information include:name 、sex、native place、age、date of birth、unit、address、postal service codes、telephone、FAX. Certainly, can create to set up a form in brief, make above each piece according to item to should a word segment.Need to point the form the main key in parties now, in order to unique marking each a record, increase register number conduct and actions unique key respectively in register form, guarantee a two records like this all different.To the database after making an above analysis, we can start establishing the database.3.set up the firm in campHere we study to establish the database how, needing to make sure the type that to establish the database first. Pass in Visual Basic the data interview control piece or data interview object ( DAO) can visit the following database:1)The database of JET, namely Microsoft Access2)The database of ISAM, such as: DBase, etc. of FoxPro3)The database of ODBC, every follow the standard of ODBC customer/ server database. Such as: Microsoft SQL Server, OracleBy any large, if develop the personal small scaled database system, use Access database comparison accommodation, to develop the big and medium-sized database system uses the database of ODBC fester. But dBase with the database of FoxPro because of already dated, unless special circumstance, do not use otherwise. In our example, chose to use the database of Access certainly. Establish the database of Access contain two kinds of methods: While establishing the database in Microsoft Access. Click" new set up" button can establish the new form. Here we main introduction the second method: The usage can see to turn the data management machine, do not need to weave the distance and then can create to set up the database. Can see to turn the data management machine is the applied procedure of a great use, it is a VB business enterprise version is supplementary with the profession version, in the catalogue\..\ Devastation\ vb\ samples\ the Visdata is next, its interface is as follows the diagram.Click the menu" document" item is next" new set up" son item" Microsoft ACCESS" son item of" edition 7.0 MDB" item. Input the new setting upthe name of the database in flick window way open" register", appear the underneath show the window way:Want the born and new form, the single shot in right key database window way flicks the menu open, then the choice" new form" ordinaries, establishing in" watch construction" dialog box appeared later on a word for wanting segment. The every time faces to join in the form new word segment, single shot" increment word segment" button, will appear of" increment word segment" dialog box."Increment word a type for" options in the dialog box, according to word segment. In our the register database that establish, the type of the each word segment.Want to notice of is, because the word segment registers the number be used unique marking record of, therefore, it can't be inputted by customer. So while defining the word's segment need to be defined for Long data type, the " automatic born word segment" item is valid, and picks out this item. Be the customer like this to input to record with other the different value every input a new record, system would on the word's segment automatically.In ACCESS database, the key word realizes with the index of, conduct and actions plait distance personnel at gather to weave the distance to the record of the form type, needs to adjust to use index. While searching, the technique of Rushmore uses the index information the excellent turning the search automatically. After completing the form definition, click" increment index" button, flick such aspen figure 5 show the window way.In window way the right side contain three optioned, its meaning, such as table,12.Increase the index dialog box options.After completing such as figure 6.Certainly, the academic association database establishes too not a dynasty the business of the one night, the reader no harm much practices once.Visit databases design and the development of the application procedures of MS Visual Basics of the databases of the SQL Server. When design a system, the customer still needs to comprehend to use to come to visit the plait distance of ask the data of SQL Server to connect. The origin was detailed to elaborate that the usage open type database conjunction (the Open Database Connectivity, ODBC) adjusts to connect the objects to connect with the class, still having the data interviews object (the Data Access Objects, the DAO) and the long-range data objects.Design and weave to write large and complicated and applied procedure's database design for the software developer is a challenge, need to choose to weave the distance language and tools, do an accommodation for the SQL Server, choose the calculate way and the data structures, still need to design the sketch customer interface and the application procedures to connect. The decision within the most important software design is applied fixed position of the procedure. In other words, design must specify the system of which parts are data, business rule, and the data entrance procedure and used for circulating the code of other part. The MS Visual Basic supports the plait distance that some databases manage the systems connect, especially SQL Server. Adjust to connect to include the ODBC and DB-Libraries to connect the, object to connect to include the data interview object (DAO), long range data object (the RDO), the OLE DB and the ActiveX Data Objects (ADO) with the class, the SQL that returns the capable SQL Server to manage the mission distributes to manage the object (the SQL Distributed management Objects, SQL-DMO) toconnect. Connect the oculars right choice can improve the whole function of system and the development speed biggest. Design the large data warehouse system needs to choose the applied model properly. Traditional customer/ service's model depends on to join in the center layer but get the improvement to become three layer models. These three layers divide the line system as three parts: each layer is responsible for providing the service:(1) Data service( the Data Service) contain the maintenance data and the operation date such as the increment, modification, deletion and backups. These services maintenance data relation and contact, support backup and instauration operation. Usually the data service is managed the system usage by the database.(2) business service( the Business Service) is handled the logic by the business rule and data to constitute, such as the data legitimacy rule, the business processing support and the record backup logics. The main purpose of these services provides the data maintenance toward the application procedure Logic.(3) expression service( the Presentation Service)( or the customer service) support customer interface, control the customer data to input to express with data.(Output) Notice in customer/ service's technical term, sometimes express the service definition as customer's machine (or head), the data service definition for server (or after carry), but the business service is in the center the layer (the middle layer). But important comprehend any two layers .The data service business service expresses the logic support GUI that the service maintenance database business rule and the processing data need, data importation and manifestation the correspondences can think to carry on between customer's machine and servers. For example, in the center the layer can think is a head.Server The physics realization of the system can carry on through many different paths. The underneath wills discuss three layer logic models three kinds of to carry out the method:1.Fat customer machine realizationMany layer (the multi tier) realizations of fat customer the machine realization three layer models of a kind of carry out the options is in the customer's on board movement business and expression services. This probably writes the most common path in the Visual Basic application procedure for the SQL Server. This kind of carries out the physics up only two layers:The server provides the data service only, this kind of method contain 2:00 shortage. First, was the applied procedure to compute the on board increment at the customer, customer's calculators need to be stronger, this will increase the system expense, because the system usually takes several customer's machines. When the system takes to have the number with thousand million of customer's machine, this kind of method will become too expensive. Another 1:00 shortage is a possible increment maintenance expenses. Move to the change of legitimacy logic and the business rule of the system and will cause upgrade customer's machine procedure each time. If the system contain customer's machine of the equal quantity, this is a problem. The biggest advantage of the machine realization in fat customer is to reduce the network discharge, if the legitimacy and the business rules need not be decide bythe database. Under this kind of circumstance, only pass the data of the legitimacy logic and can spread toward server. Be the example of the importation data legitimacy, suppose the reader to have a small form (for example national form of name) to put in customer's machine. If the data entrance mold piece checks the native watch but is not a more national name in main database, then will reduce the network discharge obviously. Another an important use is in the development process of the system. If the head developer was limited to the interview carry behind, for example, can't pass the data in the database to verify to input the legitimacy, so, this kind of method can make it right processing data.2. Thin customer machine realizationIn thin customer the machine realization, business the service locates the server, the business logic usually expresses for saving process.The Server, the saving process usages T-The SQL plait write. This kind of realization is like fat customer's machine to carry out the similar physics up only two layers.The advantage of this kind of method is to reduce the system expense, because thin customer's machine needs the less system resources, this have very important many systems of customer's machines to take. And, support the expenses to also compare the fat customer the machine system is a little less, because the code carries the concentrated control in the server.If the business rule is depend on in the data of the database, thin customer the machine realization reduces the network discharge. The main shortage of this kind of method is a saving process to lack the vivid. The Visual Basic provide stronger than the T-SQL the plait distance ability that have to have another. Notice three the thin customer of the layer model the machine physics realization sometimes is called the fat server (the fat Server) model to confuse with thin customer's machine/ server calculation model by avoid, the latter points a kind of thin customer the machine hardware equipments and techniques are for example the Citric.3. Many layer realizationMost in brief many layer realizations are three layer realizations, many possible three a kinds of the layer model physics realizations. In this kind of realization, Link the SQL Server usage data service business to serve the " thin" customer of the machine expression service data service business service of fat customer from the Visual Basic the machine expression service data business the service be an alone the progress circulate. That progress can install for serve in the data same set server of the place or at another one server of the dissimilarity. The key characteristics of this kind of realization is the data service, business to serve the different from expression serve to can do for separation of progress movement in calculator.

酒店管理系统餐饮设计论文（英文）A SOFT SYSTEMS METHODOLOGY APPROACH TO DESIGN ARESTAURANT MANAGEMENT MODEL FOR A GREAT TOURISM HOTEL Abraham Briones-Juarez, Ricardo Tejeida-Padilla, Oswaldo Morales-Matamoros Instituto Politécnico Nacional, Méxicoabrahambriones2003@.mx, rtejeidap@ipn.mx, omoralesm@ipn.mx ABSTRACTThis paper is about the design of a systemic model used in restaurants' managementinside the hotels of Great Tourism category in Mexico City, applied to the Restaurantthe Gifts of the Hotel Sheraton Centro Historico.With the purpose of establishing a Holistic vision of the work's development, the use ofthe Systems' Paradigm and concepts of Soft Systems Methodology by Peter Checklandwas determinate, since the case of study is a social system that is not only able tochoose means to reach certain goals, but also capable to select and to change them.The designed model was conceptually defined with the restructuring of the informationflows, the reorganization of the restaurant's organizational structure and the view of theelements that affect the system in its intern and external environments. Keywords: Soft System Methodology, management, restaurant, hotel, tourism. INTRODUCTIONTourism is one of the most important and dynamic segments in the current world contributing with around 11% of the world production and generates one of each elevenwork positions. It is considered that in next 20 years 1.6 million tourists will travelaround the world and they will leave a billion dollars economic spill, in Mexico thetourism sector contributes with over 7% of the national PIB and it also contributes withmore than 9% in direct and indirect work positions (Consejo de Promoción Turística,2006).Tourism has become a world level alternative to confront the setbacks of the poorcountries that look forward to develop alternatives that improve their economies bymeans of the creation, diffusion and improvement of its tourist destinations, so much ofbeaches as of cities. Such it is the case of Mexico that occupies the 7º place in tourists'reception at world level with a reception of .31% of the world tourism.In Mexico the tourist activity and therefore the hotel industry are part of one of the maineconomic activities, is enough to mention that the hotel occupation constitutes the baseto define the tourist demand.External ambientThe Federal District is one of the most prominent sites of the national territory since ithas areas that have been declared as Patrimony of the Humanity by the UNESCO,among which is the Historical Downtown and Xochimilco, considered as acosmopolitanCity that offers cultural and commercial leisure activities, the tourist importance of Mexico City resides in the business segment of tourists of that it receives,SSM Approach to Design a Restaurant Management Model2reason why it is a destination that has high occupations in its hotels on week days whiletheweekends it keeps economic rates and low occupations. Therefore the lodgingcompanies need to establish promotions packages and discounts to t he weekendtravelers, settled down in the program Dfiesta which is born like an initiative of the DFSECTUR.The Federal District harbors a series of Great Tourism category hotels that are presentedbelow with the granted category by SECTUR in stars and with the granted category bythe American Automobilist Association (AAA) in diamonds.Chart 1.

Below the departmental divisions of the Hotel Sheraton Centro Histórico are presentedwith the intention of locating the department of Food and Beverages that will be studiedalong the analysis.Figure 1.

Food and Beverages department Organisational ChartSource: F & B Policies and Procedures Hotel Sheraton Centro Histórico Manual Inside this representation, we can observe not only the hierarchy lin es but therepresentation of the information flow by means of the which the communicationchannels that give life to the restaurant system are established, composed by the Foodand Beverages area that is divided in two specific areas: on one hand the kitchen area orproduction of food and for the other one the management of the services area. This kind of structural hierarchy is designed to allow the free flow of information forthe decisions making, however, the restaurant is divided inside its management by theareas so much productive as for the services areas, maybe for a convenience in thehandling of the Food and Beverages in general. That when being examined from thesystems approach shows us the inconsistencies of the hierarchical structure, becausework cells are not being integrated under a communicative hierarchy capable to carryout functions that regulate the disorder in the system, which genera tes a lack offunctionality in the handling of the management.It is necessary to mention that the hotel restaurant system belongs to an specificallygreater area, a greater system denominated Food and Beverages by means of which, acentralized management is carried out to control the information flow s and themanagement handling, concentrating it on the section chief of the Food and Beveragesarea named: Food and Beverages Head Master .Generally, the hotels have an area manager, this person has the attribution to control theoperation, we refer to the restaurant captains, whom have under their responsibility tocontrol and to coordinate the physical operation of the establishment, is important tomention that inside the management patterns of the hotels, it is co nsidered thatmanagement or management committee is considered as the only one authorized to carry out modifications, proposals or adaptations to the operation systems, althoughthey are not directly controlling the operation of the area. This means that although it iscertain that a high hierarchy is necessary to make certain decisions, it is also certain thatthe operation, organization and planning for the right decisions making to improve theirown management, should be left in the hands of the direct area managers. Operations Head MasterF&B Head MasterExecutive Cheff Bar and Restaurant ManagerExecutive Sub CheffBanquets CheffPartie CheffRestaurant captainHostessWaitersWaiter helper CooksBars ChiefBarmanBar helperSSM Approach to Design a Restaurant Management Model5The same thing happens within the information flows since generally, the head mastersreceive all the information that concerns to the decisions making, and they take theiractions establishing a general level of management in the whole area of food andbeverages. That is to say, they consider non appropriate solutions for particular F and Bconsuming centers because they visualize all of them as homogeneous.The above-mentioned is considered as a non functional element of h ierarchicalcompetence, on the other hand it is convenient to mention that the information receivedby head masters is processed by the Food and Beverages management establishing thenecessary presage that cover its required level of economic and sales benefit, withoutconsidering or carrying out an analysis of the situation that consuming centers live atthe moment where their area managers are far from being decisions makers and onlyassume a technical role, controlling the physical operation and giving solution to theproblems that are generated during the dayOn the other hand, the headmasters generally are not appropriately prepared to establishtools or instruments that allow them to measure the way in which the actions aredeveloped inside the restaurants in a qualitative way. They consider the sales like onlyelement that indicates everything goes like it should, when the necessary thing toimprove their managerial levels is to consider the qualitative and quantitative variablesthat generate an improvement in the sales variable.Inside the current management that the hotel restaurants follow and in general in thewhole hotel, complaints and technical handlings and abilities that the supervisingpersonnel have to control such complaints are given priority. However, they are onlycentered in the possible solutions that can generate a favourable situation in the momentof the quarrel with the client, without taking in consideration the primary causes thatcaused the phenomenon, generally the bad service it is solved with granting incentivesto the clients like discounts, special prices or simply the reinstatement of the physicalproduct that constitutes the service, in this case the dishes of the restaurant thatgenerates higher costs but doesn't solve the frequent problems to which the servicesproviders face.Inside the quality controls with which the Starwood chain counts, we can find theinspection visits of the corporate to measure what they call the quality of the services,which rather refer to the execution of the standards to determine the perseverance intheir use. This revision is performed every 6 months and at the end of the inspection theexecutive committee meets with the Shopper, who informs on the obtained results.This kind of evaluations is very common inside the hotel industry where the handling ofthe standards is related with the client's satisfaction, trying to establish a level ofservice, that is to say that the quality of the service is reduced to the repetitive use ofstandards,minimizing to a very inferior scale the human potentialities that can bedirected toward better structured goals.The above-mentioned, shows one more lack of functionality in the evaluation aspect ofthe services providing.Is important to mention that the lack of functionality presented in this stage of theresearch will be recaptured for the structuring of the restaurant management model inwhich they will be given a systemic treatment to promote their improvement.SSM Approach to Design a Restaurant Management Model6DEVELOPMENTThe systems of human activity are systems models built to perform an activity with theintention of questioning the situation of the real world in a comparison phase. Contraryto the hard systems, the human activity systems or soft systems f ace disorderedproblems and human beings in social roles, reason why the methodology is used tocreate the Holón (the whole) with defined purpose and emergent property that is to saywith capacity to pursue the purpose completely (Checkland & Scholes, 1994). Description of the not structured problemNext, through the use of the soft systems methodology is presented the first image thatmakes allusion to the situation in which the problem is perceived.In this stage, it is necessary that the researcher knows the nature in which theproblematic situation is generated.

（学校代码： XXX 学号：XXX本科毕业外文文献翻译学生姓名：X X X学院：信息工程学院系别：计算机系专业：软件工程班级：软件06指导教师：X X X讲师二○一○年六月To connect SQL Server databaseFirst we introduce the basic knowledge of the database, be regarded as the warm-up exercise that study database weave distance front!1.warm-up exerciseNeeding first avowal is relation database that database knowledge that we here introduce all point. The so-called relation database is to mean data as that the form gather, passing to establish simple form an a kind of database for of relation to defining construction.I ignore the watch at how saving way in physics in the document in database is, it can see to make an a line for with row, with electronics form is similar with the row. In relation database, the line were called the record, but the row then is called word segment.This form inside each an all in formations for is a record, it including particular customer, but each record then included the same type with the word segment of the quantity: Customer's number, name etc.Form is logic set that a kind of related information that press a line of arranging with row, similar in single form in work.Each row of the word a database form inside calls a word segment. Watch is from every kind of word a definition of its containment of, each word a data for describing its implying. While creating to set up a database, the beard assign for each word segment a the piece belongs to the sex with the other according to the type, biggest length. The word segment can include every kind of word sign, arithmetic figure even sketch.An information of relevant customer deposits in the line of the form, is called record. By any large, arbitrarily two records for database form to create set up can't be same.Key be a certain word segment( or several words segment) of the form inside, it() for fast inspect but drive index. The key can be unique, and also can then the right and wrong is unique, being decided by it() whether admission repetition. Unique key can specify for main key, using each one that come to unique marking form.The norm turns the database design of mission be method that the data of buildup, but the data of buildup, should can dissolve otiose repetition, and for have the necessary information offering to check to seek the path quickly. For attaining this kind of target but separate information to the process gone to in every kind of independent form, be called the norm turn.It is complicated process to use many appointed rules to proceed the norm with the type of the different Class that norm turn. That process studies and discuss already beyond the reach of textual scope. But, the norm of the simple database in majority turn and can use the simple experience in underneath rule completes: include the form of the information of repetition must be divided into independent a few forms dissolve repetition.If we have chosen to learn 12 curricular 1000 students, the each curricular elucidation will show with the teacher 100 many- to choose that curricular and eachstudent repeat once. To avoid this kind of low efficiency, should to turn the dichotomous and independent form in form to the norm,an is used to mean the student, the another uses mean the course.Now the form was turned by the norm, so, to changes the particular and curricular course describe or" data", as long as change a record all right.Is a basic knowledge concerning database above, this is what study database plait distance must. Although the database technique is used as a course, its depth is not this space and can describe with the wide degree of, be used as the primer with simple database plait the distance should be all right already.Like, underneath we can start practicing. We usually meet the database system is to registers the system, ignoring you are in the unit, or attend what buildup, the register is to cans not help of, and it of the construction is more simple, we take a register system as an example. The analysis is once a data for involving.2. understanding the elementsFor the register, want the on the trail of information include:name 、sex、native place、age、date of birth、unit、address、postal service codes、telephone、FAX. Certainly, can create to set up a form in brief, make above each piece according to item to should a word segment.Need to point the form the main key in parties now, in order to unique marking each a record, increase register number conduct and actions unique key respectively in register form, guarantee a two records like this all different.To the database after making an above analysis, we can start establishing the database.3.set up the firm in campHere we study to establish the database how, needing to make sure the type that to establish the database first. Pass in Visual Basic the data interview control piece or data interview object ( DAO) can visit the following database:1)The database of JET, namely Microsoft Access2)The database of ISAM, such as: DBase, etc. of FoxPro3)The database of ODBC, every follow the standard of ODBC customer/ server database. Such as: Microsoft SQL Server, OracleBy any large, if develop the personal small scaled database system, use Access database comparison accommodation, to develop the big and medium-sized database system uses the database of ODBC fester. But dBase with the database of FoxPro because of already dated, unless special circumstance, do not use otherwise. In our example, chose to use the database of Access certainly. Establish the database of Access contain two kinds of methods: While establishing the database in Microsoft Access. Click" new set up" button can establish the new form. Here we main introduction the second method: The usage can see to turn the data management machine, do not need to weave the distance and then can create to set up the database. Can see to turn the data management machine is the applied procedure of a great use, it is a VB business enterprise version is supplementary with the profession version, in the catalogue\..\ Devastation\ vb\ samples\ the Visdata is next, its interface is as follows the diagram.Click the menu" document" item is next" new set up" son item" Microsoft ACCESS" son item of" edition 7.0 MDB" item. Input the new setting upthe name of the database in flick window way open" register", appear the underneath show the window way:Want the born and new form, the single shot in right key database window way flicks the menu open, then the choice" new form" ordinaries, establishing in" watch construction" dialog box appeared later on a word for wanting segment. The every time faces to join in the form new word segment, single shot" increment word segment" button, will appear of" increment word segment" dialog box."Increment word a type for" options in the dialog box, according to word segment. In our the register database that establish, the type of the each word segment.Want to notice of is, because the word segment registers the number be used unique marking record of, therefore, it can't be inputted by customer. So while defining the word's segment need to be defined for Long data type, the " automatic born word segment" item is valid, and picks out this item. Be the customer like this to input to record with other the different value every input a new record, system would on the word's segment automatically.In ACCESS database, the key word realizes with the index of, conduct and actions plait distance personnel at gather to weave the distance to the record of the form type, needs to adjust to use index. While searching, the technique of Rushmore uses the index information the excellent turning the search automatically. After completing the form definition, click" increment index" button, flick such aspen figure 5 show the window way.In window way the right side contain three optioned, its meaning, such as table,12.Increase the index dialog box options.After completing such as figure 6.Certainly, the academic association database establishes too not a dynasty the business of the one night, the reader no harm much practices once.Visit databases design and the development of the application procedures of MS Visual Basics of the databases of the SQL Server. When design a system, the customer still needs to comprehend to use to come to visit the plait distance of ask the data of SQL Server to connect. The origin was detailed to elaborate that the usage open type database conjunction (the Open Database Connectivity, ODBC) adjusts to connect the objects to connect with the class, still having the data interviews object (the Data Access Objects, the DAO) and the long-range data objects.Design and weave to write large and complicated and applied procedure's database design for the software developer is a challenge, need to choose to weave the distance language and tools, do an accommodation for the SQL Server, choose the calculate way and the data structures, still need to design the sketch customer interface and the application procedures to connect. The decision within the most important software design is applied fixed position of the procedure. In other words, design must specify the system of which parts are data, business rule, and the data entrance procedure and used for circulating the code of other part. The MS Visual Basic supports the plait distance that some databases manage the systems connect, especially SQL Server. Adjust to connect to include the ODBC and DB-Libraries to connect the, object to connect to include the data interview object (DAO), long range data object (the RDO), the OLE DB and the ActiveX Data Objects (ADO) with the class, the SQL that returns the capable SQL Server to manage the mission distributes to manage the object (the SQL Distributed management Objects, SQL-DMO) toconnect. Connect the oculars right choice can improve the whole function of system and the development speed biggest. Design the large data warehouse system needs to choose the applied model properly. Traditional customer/ service's model depends on to join in the center layer but get the improvement to become three layer models. These three layers divide the line system as three parts: each layer is responsible for providing the service:(1) Data service( the Data Service) contain the maintenance data and the operation date such as the increment, modification, deletion and backups. These services maintenance data relation and contact, support backup and instauration operation. Usually the data service is managed the system usage by the database.(2) business service( the Business Service) is handled the logic by the business rule and data to constitute, such as the data legitimacy rule, the business processing support and the record backup logics. The main purpose of these services provides the data maintenance toward the application procedure Logic.(3) expression service( the Presentation Service)( or the customer service) support customer interface, control the customer data to input to express with data.(Output) Notice in customer/ service's technical term, sometimes express the service definition as customer's machine (or head), the data service definition for server (or after carry), but the business service is in the center the layer (the middle layer). But important comprehend any two layers .The data service business service expresses the logic support GUI that the service maintenance database business rule and the processing data need, data importation and manifestation the correspondences can think to carry on between customer's machine and servers. For example, in the center the layer can think is a head.Server The physics realization of the system can carry on through many different paths. The underneath wills discuss three layer logic models three kinds of to carry out the method:1.Fat customer machine realizationMany layer (the multi tier) realizations of fat customer the machine realization three layer models of a kind of carry out the options is in the customer's on board movement business and expression services. This probably writes the most common path in the Visual Basic application procedure for the SQL Server. This kind of carries out the physics up only two layers:The server provides the data service only, this kind of method contain 2:00 shortage. First, was the applied procedure to compute the on board increment at the customer, customer's calculators need to be stronger, this will increase the system expense, because the system usually takes several customer's machines. When the system takes to have the number with thousand million of customer's machine, this kind of method will become too expensive. Another 1:00 shortage is a possible increment maintenance expenses. Move to the change of legitimacy logic and the business rule of the system and will cause upgrade customer's machine procedure each time. If the system contain customer's machine of the equal quantity, this is a problem. The biggest advantage of the machine realization in fat customer is to reduce the network discharge, if the legitimacy and the business rules need not be decide bythe database. Under this kind of circumstance, only pass the data of the legitimacy logic and can spread toward server. Be the example of the importation data legitimacy, suppose the reader to have a small form (for example national form of name) to put in customer's machine. If the data entrance mold piece checks the native watch but is not a more national name in main database, then will reduce the network discharge obviously. Another an important use is in the development process of the system. If the head developer was limited to the interview carry behind, for example, can't pass the data in the database to verify to input the legitimacy, so, this kind of method can make it right processing data.2. Thin customer machine realizationIn thin customer the machine realization, business the service locates the server, the business logic usually expresses for saving process.The Server, the saving process usages T-The SQL plait write. This kind of realization is like fat customer's machine to carry out the similar physics up only two layers.The advantage of this kind of method is to reduce the system expense, because thin customer's machine needs the less system resources, this have very important many systems of customer's machines to take. And, support the expenses to also compare the fat customer the machine system is a little less, because the code carries the concentrated control in the server.If the business rule is depend on in the data of the database, thin customer the machine realization reduces the network discharge. The main shortage of this kind of method is a saving process to lack the vivid. The Visual Basic provide stronger than the T-SQL the plait distance ability that have to have another. Notice three the thin customer of the layer model the machine physics realization sometimes is called the fat server (the fat Server) model to confuse with thin customer's machine/ server calculation model by avoid, the latter points a kind of thin customer the machine hardware equipments and techniques are for example the Citric.3. Many layer realizationMost in brief many layer realizations are three layer realizations, many possible three a kinds of the layer model physics realizations. In this kind of realization, Link the SQL Server usage data service business to serve the " thin" customer of the machine expression service data service business service of fat customer from the Visual Basic the machine expression service data business the service be an alone the progress circulate. That progress can install for serve in the data same set server of the place or at another one server of the dissimilarity. The key characteristics of this kind of realization is the data service, business to serve the different from expression serve to can do for separation of progress movement in calculator.

外文文献资料A Comparative Study of Web Application Design ModelsUsing the Java TechnologiesAbstract.The Servlet technology has been the most widely used technology for building scalable Web applications. In the events, there are four design models for developing Web applications using the Java technologies: Model 1, Model2, Struts, and JavaServer Faces (JSF). Model 1 employs a series of JSP pages; Model 2 adopts the Model-View-Controller pattern; Struts is a framework employing the Model 2 design model; and JSF is a new technology that supports ready-to-use components for rapid Web application development. Model 1 is not recommended for medium-sized and large applications as it introduces maintenance nightmare. This paper compares and evaluates the ease of application development and the performance of the three design models (Model 2, Struts, and JSF) by building three versions of an online store application using each of the three design models, respectively.1 IntroductionToday, Web applications are the most common applications for presenting dynamic contents. There are a number of technologies for building Web applications, the most popular of which is the Servlet technology . This technology gains its popularity from its superiority over other technologies such as CGI and PHP .Servlets are cumbersome to develop, however, because sending HTML tags requires the programmer to compose them into a String object and send this object to the browser. Also, a minor change to the output requires the servlet to be recompiled. To address this issue, Sun Microsystems invented JavaServer Pages (JSP) . JSP allows HTML tags to be intertwined with Java code and each page is translated into a servlet. A JSP page is a servlet. However, compilation occurs automatically when the page is first requested. As a result, changing the outputdoes not need recompilation. In addition, JSP enables the separation of presentation from the business logic through the use of JavaBeans and custom tag libraries. The norm now in developing Javabased Web applications is to use servlets along with JavaServer Pages.In the later development, there are a number of design models for building servlet/JSP applications: Model 1, Model 2, Struts , and JSF . Model 1 and Model 2 were first mentioned in the early specifications of JSP. Model 1 strictly uses JSP pages, with no servlets, and Model 2 uses the combination of both servlets and JSP pages. The terms of Model 1 and Model 2 have been used ever since. Model 1 is suitable for prototypes and very small applications, and Model 2 is the recommended design model for medium sized and large applications.As Model 2 gained more acceptances in the industry, an open source initiative to build the Struts Framework was initiated. Struts perfects Model 2 by providing the controller part of the Model-View-Controller of Model 2. In addition, Struts provides better page navigation management and several custom tag libraries for more rapid development. Despite its steep learning curve and the fact that it was never defined in any specification, Struts has been gaining popularity as the alternative to Model 2.JavaServer Faces is built under the Java Community Process under JSR-127.Sun Microsystems proposed this technology in the hope that JSF will be the ultimate model for building Java Web applications. The most important feature of JSF is the availability of ready-to-use components such as extensible UI components, easy page navigation, input validators, data converters and JavaBeans management.The problem facing servlet/JSP programmers are to choose the most appropriate design model. Clearly, JSF provides a better solution in regard to development time. However, some people are not sanguine to adopt this technology for fear of performance penalty due to the overhead of the JSF implementation.We build three versions of an online store application named BuyDirect using Model 2, Struts and JSF. The parameters compared are the number of lines of code, the number of classes, and the performance measurement results. We investigate which of the design models allows the most rapid development process. Weevaluate the performances of the applications built upon these models. We provide some suggestions to perfect the existing design models to make development more rapid.The rest of the paper is organised as follows. Section 2 discusses the issues in Web development. Section 3 explains how the three design models address these development issues. Section 4 provides the details of the hardware and software used in these experiments. Section 5 presents the experiment results and analysis. Section 6 reviews the related work. Section 7 concludes by offering some suggestions to improve the existing design models.2 Java Web Development IssuesAll Java Web development uses the Servlet technology as the underlying technology. As such, all Java Web applications have certain issues that need to be addressed:●User Interface. The user interface is what the client browser renders as HTMLtags. Any server-side component used in the application must be encoded into the corresponding HTML elements. Besides for displaying the content and data, the user interface is also responsible in receiving input from the user.●Input Validation. User input needs to be validated. There are two types of inputvalidation, server-side and client-side. As the name implies, the server-side input validation is performed on the server after the input reaches the server.Client-side input validation is done on the browser, usually by using JavaScript or other scripting languages. The advantages of using client-side input validation are prompt response and reducing the server workload. The server-side input validation should always be performed regardless the presence of client-side validation because there is no guarantee the user browser's scripting feature is being on and malicious users can easily work around client-side validation.●Model Objects. Model objects in Java-based Web applications are in the formsof JavaBeans. Model objects make up the Model part of the MVC based design model. A model object can be used to bind a component value to be used at a later stage. In addition, it can encapsulate business logic required forprocessing.Page Navigation. Almost all Web applications have multiple pages that the user can navigate from one to another. All MVC-based design models use a servlet as the Controller part. This servlet also acts as the sole entry point to the application. Which page to be displayed after the current request is determined by the value of a specified request parameter. Managing page navigation is critically important.3 Web Application Design ModelsThe Model 2 design model is based on the Model-View-Controller (MVC) design pattern. As explained by Burbeck , there are three main modules in MVC, the Controller, the View, and the Model. The Controller acts as the central entry point to the application. All user interactions go through this controller. The View contains the presentation part of the application, and the Model stores data or encapsulates business logic of the application. In the later development, the Struts Framework provides a common framework to easily build Model 2 applications. Then, the last initiative is the JavaServer Faces, which also employs the MVC design pattern.In the following sections, we discuss these three design models and explain how each design model addresses the development issues specified in the previous section.3.1 Model 2A Java Web application that is based on the Model 2 design model has one servlet(called the Controller servlet) that serves as the Controller part. All requests are first handled by this servlet, which immediately dispatches the requests to the appropriate views using RequestDispatcher objects. Views in the Model 2 design model are represented by JSP pages. To store data, a Model 2 application uses JavaBeans, which are the Model part of the application. In addition to storing data, the JavaBeans also encapsulate business logic. Each HTTP request carries an action parameter that indicates which view to dispatch this request to. The programmer must code the HTML tags for user interface in all JSP pages in theapplication and write input validation code. In addition, the model objects are managed by individual JSP pages.3.2 StrutsThe Struts Framework is an improvement of the Model 2 design model. It provides a default Controller servlet so that the user does not have to write and compile one. Struts alleviates the task of page navigation by allowing navigation rules to be present in its application configuration file (an XML document). Changes to the navigation rules do not require recompilation of a Java servlet class. In addition to easier page navigation, Struts provides custom tag libraries that define tags representing HTML elements. One of these tags is used for error handling and Struts is therefore capable of displaying localized error messages in support for internationalization. Struts applications use JavaBeans as their models, just like the Model 2 design model. In addition, Struts programmers have to write their own input validation code.3.3 JSFJSF also employs a controller servlet that is called FacesServlet. This servlet is the only entry point to a JSF application. JSF also uses JSP pages as its views and JavaBeans as its model objects. Unlike Model 2 and Struts, however, JSF provides ready-to-use user interface components that can be written on JSP pages. Upon an invocation of a page of a JSF application, the FacesServlet constructs a component tree that represents the JSP page being requested. Some of the components can also trigger events, making JSF event-driven. For page navigation, JSF uses an approach similar to Struts, i.e., by allowing navigation rules to be defined in an application configuration file (again, an XML document).What distinguishes a JSF application from non-JSF servlet/JSP application is that JSF applications are event-driven. The user interface of a JSF application is one or many JSP pages that host Web components such as forms and input boxes. These components are represented by JSF custom tags and can hold data. A component can be nested inside another, and it is possible to draw a tree of components. Just as in normal servlet/JSP applications, you use JavaBeans to storethe data the user entered.4 Function EnvironmentThe software and hardware details for our experiments are described below.4.1 The Servlet ContainerA Java Web application runs in a servlet container, which is the engine that processes the incoming HTTP requests for the resources in the application. For this research project, we use Tomcat, an open source servlet container from the Apache Software Foundation. The version we use is 6.0.Basically, a servlet container processes a servlet by performing the following tasks:- Creating the HttpRequest Object- Creating the HttpResponse Object- Calling the service method of the Servlet interface, passing the HttpRequest and HttpResponse objects.4.2 Testing ClientsFor performance testing, we emulate multiple users using JMeter 1.9 , also from the Apache Software Foundation. JMeter allows the user to choose the number of threads to perform testing. Each thread emulates a different user. JMeter also lets us choose how many times a test will be done. To test a Web application using JMeter, you direct requests to certain IP address, context path, and port number. You can also specify request parameters to be included in each HTTP request. As the output, JMeter notifies the response time of the server in milliseconds for a test. From the response time, we derive the number of hits/seconds the server is capable of serving.4.3 HardwareWe use different computers for running the applications and for testing, so as to obtain maximum performance measurement accuracy. The computer running the application is a XP machine having the following hardware specifications: IntelCore 1GHz CPU with 1G RAM. The computer running the testing clients is a Windows 2000 machine running JMeter. The computer has the following specifications: Intel Core 1GHz CPU with 1G RAM.5 ResultsWe obtain experimental results in two categories: the ease of development and performance. The ease of development category compares the number of classes and the number of lines of code. These numbers indicate how easy it is to develop an application by following a certain design model. An application with the fewer number of classes or the number of lines of code indicates that the application is relatively easier to build. The application with the more number of classes indicates that the application takes more time to develop.The performance measurement results are obtained by comparing two operations. The Search operation is the most common operation in such an application,and the Browse operation.5.1 Ease of Application DevelopmentAs Table 1 shows, it takes the most effort to implement the Model 2 design model. Using Struts alleviates the problem a bit, and the best saving in the development comes if one uses JSF.Table 1. The number of classes and the number of lines for the applications under studyThe Model 2 design model is characterised by the presence of a Controller servlet and a number of JavaBeans classes (as the Model) and JSP pages (as the Views). The Controller servlet is responsible for page navigation rules that employa series of if statements. Model 2 application programmers must also code for the input validation that in this research is implemented inside a number of custom tag libraries. The other classes in the Model 2 design model are custom tag library and the tag library descriptors responsible for input validation and data display. In fact, input validation takes 590 lines of code, or almost 30% of the total amount of code.In the Struts application, the Controller servlet is provided by the framework, therefore a Struts programmer saves time for not having to write one. However, he/she still needs to write page navigation rules in the Application Configuration file, which is easier than writing a servlet because the Application Configuration file can be edited using a text editor and no compilation is necessary. Input validation must still be done manually, even though the Struts Framework provides an error handling mechanism. The number of classes and the number of lines of code for input validation are almost similar to the Model 2 application. In Struts, the other classes are Action classes to which the default Controller servlet dispatches requests.In JSF input validation comes free through the availability of validator component. As a result, a JSF application developer can skip this task. In addition, page navigation takes the same course as Struts, i.e. by utilising an Application Configuration file. The other classes in JSF are a ContextListener, an ActionListener, and a Database utility class.5.2 Performance MeasurementFor each operation, we measure the server response time (in milliseconds) for 1 to 10 concurrent users. The number of users is specified by setting the number of threads in Jmeter. Each test is conducted 10 times and the average is taken. Each operation is discussed further is the following sub-sections.5.2.1 Search OperationThe Search operation whose name or description matches the keyword. There is one SQL SELECT statement performed. Figure 2 compares the three versions of applications for the Search operation.Fig. 2. The performance comparison for the Search operation For the Model 2 application, the average server response time for one user is 173 ms and for 10 users is 919 ms. For the Struts application, these numbers are 189 ms and 900 ms, respectively. For the application built using JSF, the average server response time is 210 ms for one user and 932 ms for 10 users. The increase of the response time is proportional to the increase of the number of concurrent users, which means that the server is still able to cope with the load.The Model 2 application has the least overhead, therefore the average performance should be better than the Struts and JSF applications. However, the Struts application performs as well as the Model 2 application. This is because the server has enough memory to load all Struts libraries required to run Struts. Also, note that page navigation rules in Struts are loaded and stored in an object called ActionMapping. Therefore, given an action request parameter, the next page of navigation is obtained through a look-up. On the other hand, the Model 2 application uses a series of if statements to find the next page of navigation, given the action request parameter.The JSF application performs slightly worse than the other applications in almost all numbers of concurrent users. This could be due to the time taken by the JSF implementation to construct a component tree for each page requested. However, the difference in server response time between JSF and other applications is not that significant.5.2.2 Browse OperationThe Browse operation,like the Search operation, there is one SQL SELECT statement performed. Figure 3 gives the test results for this operation.Fig. 3. The performance comparison for the Browse operation On average, the Model 2 application performs the best because it has the least overhead. The average server response time is 111 ms for one user and 899 ms for 10 users. The Struts application has comparable performance, with one user average server response time of 180 ms and 10 user response time of 920 ms. The JSF lacks a bit behind the two applications with these numbers being 190 and 1009 ms respectively. The increase of the server response time is proportional to the increase of the number of concurrent users, which means the server is able to serve those users well. The average performance measurement results of the Browse operation are very similar to the ones for the Search operation because the database operations of both operations are also similar.6 Related WorkCompare the performance of database-based Web applications using Java servlets, PHP version 3, and Common Gateway Interface (CGI). After a series of benchmark tests that performs data retrieval from a MySQL database, find that the solution of Java servlets with persistent database connection has the best performance. PHP3 using persistent database connections performs fairly well when compared to the CGI solution,also mention the advantages of using Java servlets. According to these authors. Java servlets are an excellent choice to meet the requirement of e-commerce (such as online shopping) applications and are ableto handle client requests in a highly interactive mode.Comparing PHP 4, Java servlets, and Enterprise JavaBeans. Measure the performance of these three architectures using two applications. Study reveals that PHP4 is more efficient than Java servlets, and the EJBs perform even worse than servlets. However, note that servlets, being part of the Java solution, provides the flexibility of being able to be ported to another system with a different operating system.7 ConclusionWe find that it is most rapid to build Web applications using JSF. Model 2 applications are the least rapid but give the best performance. Struts applications sit in the middle of the other two design models in both comparisons.We make some suggestions that could improve the Servlets technology in general and enhance the performance of applications based on both design models.●Struts. Struts is not based on any specification and there is no documentationthat discusses its internal working. Therefore, it is hard to know what have been implemented and what could be improved.●The Servlets Technology. The Servlet 2.3 Specification does not define anycaching mechanism. There is no mention of caching in the upcoming Servlet2.4 Specification either. Despite the dynamic nature of the content of a Webapplication, some contents do not change very often. For example, the categories of products that a user can browse in an online store application probably only change once in a month. If those semi-static contents must be generated from the database every time they are requested, a lot of programming resources will be wasted. Servlet programmers get around the absence of caching by writing an object that caches certain content. However, since there is no standard for caching, many programmers write the same piece of code again and again.●Model 2.The main drawback is that the page navigation rules are hard-coded inthe Controller servlet. This means any minor change to the program flow will require the Controller servlet to be re-compiled. The solution to this problem is to provide a mapper that reads the page navigation rules when the applicationstarts. The code could be conveniently written in the init method of the Controller servlet. This method is only executed once, i.e. the first time the servlet is loaded into memory. If the properties file needs to be re-read every time it changes, the programmer can check the timestamp of the properties file for each request, and compares it with the previous read of this file. If the timestamp is more current than the previous read, the mapper can be re-constructed. This feature can be enabled and disabled by using an initial parameter in the Context object. At the development phase, this feature should be enabled. At deployment, this feature should be off. The use of the properties file to store the page navigation rules also makes it possible to avoid a series of if statements in the Controller Servlet, which can be time-consuming for every request. Instead, a HashMap can be used, with action request parameters as keys and the next JSP pages as values. The other disadvantage of this design model is the absence of standard components for input validation and user interface. However, this has been solved in JSF.JSF. JSF provides solutions to common problems in Web development, such as page navigation management, UI components and input validators. However, because this technology is still very young, there are not too many UI components available, forcing programmers to combine JSF with non-JSF servlets/JSP pages. JSF is event-driven. JSF programmers determine the behavior of a JSF application by writing event listeners, just like those listeners in a Swing application. In JSF version 1.0, there are currently two types of events that can be triggered: ActionEvent and ValueChangedEvent. However, this is good enough to provide sufficient level of interactivity between the application and its users. Adding more types of events will definitely make JSF more appealing.References［1］．Burbeck, S., Applications Programming in Smalltalk-80: How to use Model-View-Controller(MVC),/users/smarch/st-docs/mv c.html, 1987.［2］．Cecchet, E., Chanda A., Elnikety S., Marguerite J., Zwaenepoel W.:Performance Comparison of Middleware Architectures for Generating Dynamic Web Content.
