英文原文The Active Server Pages( ASP) is a server to carry the script plait writes the environment, using it can create to set up with circulate the development, alternant Web server application procedure. Using the ASP cans combine the page of HTML, script order to create to set up the alternant the page of Web with the module of ActiveX with the mighty and applied procedure in function that according to Web. The applied procedure in ASP develops very easily with modify.The HTML plait writes the personnel if you are a simple method that a HTML plait writes the personnel, you will discover the script of ASP providing to create to have diplomatic relation with each other page. If you once want that collect the data from the form of HTML, or use the name personalization HTML document of the customer, or according to the different characteristic in different usage of the browser, you will discover ASP providing an outstanding solution. Before, to think that collect the data from the form of HTML, have to study a plait distance language to create to set up a CGI application procedure. Now, you only some simple instruction into arrive in your HTML document, can collect from the form the data combine proceeding analysis. You need not study the complete plait distance language again or edit and translate the procedure to create to have diplomatic relation alone with each other page.Along with control to use the ASP continuously with the phonetic technique in script, you can create to set up the more complicated script. For the ASP, you can then conveniently usage ActiveX module to carry out the complicated mission, link the database for example with saving with inspectional information.If you have controlled a script language, such as VBScript, JavaScript or PERL, and you have understood the method that use the ASP.As long as installed to match the standard cowgirl in the script of ActiveX script engine, can use in the page of ASP an any a script language. Does the ASP take the Microsoft? Visual Basic? Scripting Edition ( VBScript) with Microsoft? Script? Of script engine, like this you can start the editor script immediately. PERL, REXX with Python ActiveX script engine can from the third square develops the personnel acquires. The Web develops thepersonnel if you have controlled a plait distance language, such as Visual Basic, you will discover the ASP creates a very vivid method that set up the Web application procedure quickly. Pass to face to increase in the HTML the script order any, you can create the HTML that set up the applied procedure connects. Pass to create to set up own the module of ActiveX, can will apply the business in the procedure logic seal to pack and can adjust from the script, other module or from the other procedure the mold piece that use.The usage ASP proceeds the calculating Web can convert into the visible benefits, it can make the supplier of Web provide the alternant business application but not only is to announce the contents. For example, the travel agency can compare the announcement aviation schedule makes out more; Using the script of ASP can let the customer inspect the current service, comparison expenses and prepare to book seats.Include too can lower in the Windows NT Option Microsoft in the pack Transaction Server ( MTS) on the server complexity of constructing the procedure with expenses. The MTS can resolve to develop those confidentialities strong, can ratings of and the dependable Web applies the complexity problem of the procedure. Active Server Pages modelThe browser requests from the server of Web. Hour of asp document, the script of ASP starts circulating. Then the server of Web adjusts to use the ASP, the ASP reads completely the document of the claim, carry out all scripts order any, combining to deliver the page of Web to browser.Because script is on the server but is not at the customer to carry the movement, deliver the page of Web on the browser is on the Web server born. Combining to deliver the standard HTML to browser. Because only the result that there is script returns the browser, so the server carries the not easy replication in script. The customer cans not see to create to set up them at script order that the page that view.We introduce the Basic form of the database language known as SQL, a language that allows us to query and manipulate data on computerized relational database systems. SQL has been the lingua franca for RDBMS since the early 1980s, and it is of fundamental importance for many of the concepts presented in this text. The SQLlanguage is currently in transition from the relational form (the ANSI SQL –92 standard) to a newer object-relational form (ANSI SQL -99, which was released in 1999). SQL-99 should be thought of as extending SQL-92, not changing any of the earlier valid language. Usually, the basic SQL we define matches most closely the ANSI SQL standards basic subsets, called Entry SQL -92 and core SQL-99 that are commonly implemented; our touchstone in defining basic SQL is to provide a syntax that is fully available on most of the major RDBMS products[7].We begin with an overview of SQL capabilities, and then we explain something about the multiple SQL standards and dialects and how we will deal with these in our presentation.We will learn how to pose comparable queries in SQL, using a form known as the Select statement. As we will see, the SQL select statement offers more flexibility in a number of ways than relational algebra for posing queries. However, there is no fundamental improvement in power, nothing that could not be achieved in relational algebra , given a few well-considered extensions. For this reason, experience with relational algebra gives us a good idea of what can be accomplished in SQL. At the same time, SQL and relational algebra have quite different conceptual models in a number of respects, and the insight drawn from familiarity with the relational algebra approach may enhance your understanding of SQL capabilities.The most important new feature you will encounter with SQL is the ability to pose queries interactively in a computerized environment. The SQL select statement is more complicated and difficult to master than the relatively simple relational algebra, but you should never feel list or uncertain as long as you have access to computer facilities where a few experiments can clear up uncertainties about SQL use. The interactive SQL environment discussed in the current chapter allows you to type a query on a monitor screen and get an immediate answer. Such interactive queries are sometimes called ad box queries. This term refers to the fact that an SQL select statement is meant to be composed all at once in a few type written lines and not be dependent on any prior interaction in a user session. The feature of not being dependent on prior interaction is also down as non-procedurality. SQL differs in this way even from relational algebra, where a prior alias statement might be needed inorder to represent a product of a table with itself. The difference between SQL and procedural languages such as java or c is profound: you do not need to write a program to try out an SQL query, you just have to type the relatively short, self-contained text of the query and submit it .Of course, an SQL query can be rather complex . A limited part of this full form, know as a sub-query, is defined recursively, and the full select statement form has one added clause. You should not feel intimidated by the complexity of the select statement, however. The fact that a select statement is non-procedural means that it has a lot in common with a menu driven application, where a user is expected to fill in some set of choices from a menu and then press the enter key to execute the menu choices all at once. The various clauses of the select statement correspond to menu choices: you will occasionally need all these clauses, but on not expect to use all of them every time you pose a query.Observed reliability depends on the context in which the system s used. As discussed already, the system environment cannot be specified in advance nor can the system designers place restrictions on that environment for operational systems. Different systems in an environment may react to problems in unpredictable ways, thus affecting the reliability of all of these systems. There for, even when the system has been integrated, it may be difficult to make accurate measurements of its reliability.Visual Basic Database Access prospectsWith the recent Web application software and the rapid development of the existing data stored in diverse forms, Visual Basic Database Access Solutions faces such as rapid extraction enterprises located in the internal and external business information with the multiple challenges. To this end Microsoft, a new database access strategy "unified data access" (UniversalDataAccess) strategy. "Unified data access" to provide high-performance access, including relational and non-relational data in a variety of sources, provide independent in the development of language development tools and the simple programming interface, these technologies makes enterprise integration of multiple data sources, better choice of development tools, application software, operating platforms, and will establish a maintenance easysolution possible.汉语翻译Active Server Pages（ASP）是服务器端脚本编写环境，使用它可以创建和运行动态、交互的Web 服务器应用程序。

计算机毕业设计ASP外文翻译信息学院毕业设计科技文献翻译《The Design and Implementation of ASP WebSite News Management Systems 》《asp的网站新闻管理系统的设计与实现》姓名王磊专业软件工程学号202113880250 班级 2 班指导教师王立波12021年 9月AbstractThe use of ASP and SQL technology news site management system, to achieve the dynamic management of the news Web site, making the management of information more timely, efficient, improve the work efficiency. At the same time, the development of systems theory, systems and design features are introduced.[Key word] ASP，SQL，news management，databaseWith the popularization of Internet, more and more companies set up their own WWW sites, enterprises can display products through the website, publishing the latest developments, with users sharing and communication to establish contact with partners, as well as e-commerce. Information Management System which is an enterprise Web site an important part of it bears a double role, on the one hand, the dynamic can be used to release the new product or new development projects, on the other hand, the timely notice to their customers business performance, Progress in technology and research and development, in particular, recommend or preferential projects, products and services to attract customers, expand customer base.Management of traditional news sites in two ways, one static HTML page, update the information needed to re-create the page and then upload the page and modify the corresponding links, the efficiency of this approach is too low because we have little use. The second is based on ASP and scripting languages, dynamic Web pages and databases, through the application of procedures to deal with news, this is way more popular. However, due to the limitations of ASP allows the system itself, there are some insurmountable flaws, and technology has taken on the system performance has been greatly improved, the main performance in the following aspects:1. ASP page to open as a result of each must be compiled to explain the process, so when the page2opens in the rate of repeated there is no upgrade, and only need a page do not need to recompile compiled until the page has been modified or Web Application process restarted. This makes the speed in a number of visits has greatly improved.2. As the ASP does not provide any output data for the content of the components, so writing a database using ASP page can use the Record Set Object ADO to read records of transaction, while the ASP provided through the DataGrid, such as database and database components can be directly Contact.3. ASP support real-time application updates. Administrators do not haveto turn off the network server or even do not have to stop running the application can update the application on file. Application documents will never be locked, so even when the program runs in the paper can be overwritten. When the document is updated, the system will convert to the new moderate version.4. ASP take the \approach to the preparation of the code makes the code easier to prepare, structure more clearly, reducing the system development and maintenance of the complexity and the cost of.1 System Development Principle1.1 The System Architecture Model of ASP-based TechnologyASP is a three-tier system structure: UI Layer, Business Logic Tier anddata layer.UI layer is responsible for interaction with the user, receiving userinput and server-side data from present to clients.Business Logic Tier is responsible for receiving requests from browser requests to the data layers and at the same time the results of the requestsent to the browser. It consists of Web Forms, XML Web services and service composition components. Web Forms which is the core of the application, it is presented to customers based on data and information as well as to respond to and deal with customers and display interactive Web form generated based on information and data.Data layers to manipulate data through the layer for businesslogic to provide data services, such as storing the results of data manipulation and return to the results of data retrieval.1.2 The principle of access to the database 3Connected with the database, provide the following three kinds of ways: through ODBC connected; connected through OLEDB; directly connected with the SQL Server. Application of three kinds of ways as a result of differencesin levels, making the efficiency from low to high, high to low independence. Connected to the database for data processing, there are two kinds of ways,that is, through a Dataset to the isolation of heterogeneous data sources, and the other is a stream to read from the data source (Data Reader mode).Traditional application is to create a connection to the database, in the process is running the whole way to maintain connections to the design. taken disconnected mode data structure. When a browser requests a page to the Web server, the server to deal with this request, the requested pageand send to your browser, and then connection was disconnected until the next browser request issued. Another innovation is the introduction of a data set (Dataset). A data set is the relationship between memory map to provide high-speed data buffer. Data set of data sources know that they can be adopted by the programor transferred from the data warehouse data were generated, to fill.Regardless of where the data acquisition, data sets are the same procedurethrough the use of templates to be operated, and it's potential to use the same data buffer.2 Systems Functional Designs2.1 Systems Function StructuresThe news management system in Windows 2000 Server operating system platforms, Web server IIS, the database server for Microsoft SQL Server2000, development tools used in Microsoft Visual Studio. NET and DreamWeaver. Its work processes as follows: the user login through the authority to determinethe general user can only browse, read and query information, registered users can be completed in addition to the ordinary user, but also can enter information for news management module input, modify, and delete operations.In addition to registered users outside the system administrator can only be recorded on its own news operation for excision.2.2 Systems Function Characteristics(1) Simple, user-friendly: complete control of page layout, making information easier entry work;4many options including news categories, such as the source of departments only need to click the mouse can be completed; In addition, the follow-up message also appears allow users to clear their own operations.(2) Can be seen immediately: the handling of the press (including the entry, modify, delete) will be the corresponding column on the home page is displayed to \release, immediate results\function.(3) Function: include common site in all aspects of information management: information input, browse, delete, modify, search and other aspects, the full realization of the Web site of the real-time information management requirements.(4) To facilitate transplantation: for different enterprises, with some slight modifications need to be able to develop for the company's Web site features news management system.3 Systems Detailed DesignsCore functions of the system through a number of functional modules achieved. Specific design process is as follows:⑴ System login: The module responsible for the user are divided into general users and registered users to achieve the management of user rights.(2) News View: The module is responsible for all the news page web site lists information, including the title, type, source and date field departments, and each title has been made news a hyperlink, click the page they will be able to Jump news reader.(3) News reader: in other pages or click the title link to read into the news pages, at this time, detailed information of each information will be removed, including the content, title, keywords, and relatively fixed in accordance with the format placed in different pages region, the use of all the news about the same page layout, only the contents of the field corresponding to different In addition, the location of other pages can be dynamically placed in other components, such as web site logo, such as the page banner ads link to pictures, this can be easily to achieve the effect of illustrations in reading.(4) News Inquiry: The module provides a press inquiry, type to be selected to find the content and classification of information can quickly find the information in line with the conditions and results output.(5) News Management: The module listed in the registry is responsible for the registration page the user has issued a news and information and did not delete, the user can press to delete the article, modify.

Technology And SQL Server is based on the common language of compiler operation of the procedure, its strength and stability, can make it runs on the Web application of software developers almost all of the platform. The common language of basic library, information mechanism, data interface treatment can seamlessly integrate into the Web applications. is also independent language language - feasibility of, so, you can choose a kind of the most suitable for your language to write your program, or put your program in a number of language to write, now support with c # (c + + and Java combination), VB, Jscript, c + +, F++. In the future, such a variety of program language collaborative working ability to protect your present based on COM + development program, can complete transplant to . generally fall into two kind of development language, using the and c #, c # relatively common, because it is unique language, using the VB programming is used, suitable for VB programmers, if before new , no other development experience with language, suggest direct study c # can. to run some very common tasks such as form submission of client identity authentication, distribution system and website configuration became very simple. For example page framework allows you to build your own user boundary surface, make it different from common VB - Like interface. using a character basis, classification of the allocation system, make your server environment and application Settings more simple. Because configuration information is stored on simple text, new Settings may need not start local administrator tools can be achieved. Known as the "Zero Local under the" philosophy that application development based on the more specific, and quick. An application in a server system installation simply copy some must file, do not need system reboot, everything is so simple. Multiprocessor environment reliability has been deliberately designed as a can be used for multiprocessor development tool, it on a multiprocessor environment with special seamless connection technology, will greatly increase speed. Even if you now my application software is developed for one processor, future multiprocessor runtime don't need any change can improve their efficiency, but now the ASP but cannot do this. Custom sex and expansibility design is an important consideration let web developers in their own code define your own "plug - in" module. This with the original included relation is different, can join his definitions of how components. Website program development never so simple. Security Windows based certification technology and every application configuration, you can ensure that your original procedures are absolutely safe. grammar in the very great degree with ASP compatible, and it offers a new programming model and structure, it can create a loft and stability better applications, and provide a better security protection. Can pass in existing ASP application gradually add function, at any time enhancement ASP application function. is an already compiled, based on environment, based on general language program in the server. A program in the server's first run, compile than ASP instant explanation program to a lot faster speed and can use compatible with the languages (including Visual , using c # and .) creation applications. In addition, any application can be used throughout Framework. Developers can conveniently to obtain these technical advantages, including custody of the common language runtime type safety, environment, inherit, etc. can seamlessly with WYSIWYG HTML editor and other programming tools (including Microsoft Visual ) work together. This not only make the Web development more convenient, but also can provide these tools must provide all the advantages, including developers can be used to will server controls drag-and-drop Web page GUI and fully integrated debugging support. When creating application, the developers can use Web form or XML Web services for, or in any way they deem fit combined. Each function can get the same structural support, make you can use identity verification scheme, the cache often use of data, or for application configuration for custom. If you have never development of a Web site procedures, so it's not for you, you should at least master some HTML language and simple Web development terms (but I believe if interested can be quickly grasp). You don't need to previous ASP development experience (of course experienced better),but you must understand interactive Web application development concepts, ranging form, the script, and data interface concept, if you have these conditions, then you can be in world begins to soar. is not only the Active Server brief (ASP) next version, and is a built in common language program structure that can be used to a Web Server to build a powerful Web applications. provides many Web development mode than now great advantage. operation framework is divided into several stages: With the Web server in IIS news flow stage. page in the news dispatch. page in the message handling. original design conception, is to make the developer as VB development tool that can use event-driven type program development mode (-) - Driven to Model the method to develop web pages with application, if want to use ASP technology to achieve this jop, use must use a large number of ancillary information, such as the query string or form field data to identify and judge the object of source, Event flow and the called function, etc., need to write code is quite, but very ingenious use of form fields and JavaScript scripts to events hidden transfer Model.In when run, there are often web round-trip action (round - trip), in the called picker, in in traditional ASP technology, judge web of back is needed by developers themselves to write, , developers can use brief. IsPostBack function to judge whether for first run (when found HTTP POST requirement of data is null), it will ensure that controls events will only run again, but it has a shortcoming (based on HTTP POST, the defect), is when the user use the browser's renovatesthe function (hit F5 or refresh button) refresh web, the last time running events will be run again, if we are to avoid this situation, must want to force the browser cache can empty.State management (state management) in Web applications, it is always very important topic, good condition management to help developers to develop with state to sustain the applications (such as work flow type Application or e-commerce applications), but state management function may view Application status and thedeployment of information sharing degree chooses in , divided into the server configuration management and client state management, client state management for ViewState and Cookies, server Session state management is to apply object. Their cultures depends on: ViewState is encrypted data streams, and HTML together the output to client. Cookies are encrypted (also don't encryption) of small data, and HTML is different, it can high-speed slow existing client browser. Is the server Session state preservation mechanism, each client all have independent space (in browsers run individual to fu with only SessionID values). Apply is server-side state preservation mechanism, but the client Application all Shared one state data.State management in a single server, can be stored in the server's memory, but if in the large-scale Web site, use a lot of Web server to implement the Load balance (-) processing, Load there will be stored in the state where on the problem, so it needs a can in every Web server storage medium between state, such as independent servers or database, etc. In in support of four state storage medium: InProc: storage and the same operation process (state) procedure in -, suitable for a single server status of storage. StateServer: storage in state server (state server), suitable for cross-server state storage, but because it USES communication port, so in use should be paid attention to the firewall problem. SQLServer: stored in separate SQL Server database, suitable for cross-server state storage. Custom: on the realization of state provider (state provider).Database ManagementDatabase records and files must be organized to allow retrieval of the information. Early system were arranged sequentially (i.e., alphabetically, numerically, or chronologically); the development of direct-access storage devices made possible random access to data via indexes. Queries are the main way users retrieve database information. Typically the user provides a string of characters, and the computer searches the database for a corresponding sequence and provides the source materials in which those characters appear. A user can request, for example, all records in which the content of the field for a person’s last name is the word Smith.The many users of a large database must be able to manipulate the informationwithin it quickly at any given time. Moreover, large business and other organizations tend to build up many independent files containing related and even overlapping data, and their data, processing activities often require the linking of data from several files. Several different types of database management systems have been developed to support these requirements: flat, hierarchical, network, relational, and object-oriented.In flat databases, records are organized according to a simple list of entities; many simple databases for personal computers are flat in structure. The records in hierarchical databases are organized in a treelike structure, with each level of records branching off into a set of smaller categories. Unlike hierarchical databases, which provide single links between sets of records at different levels, network databases create multiple linkages between sets by placing links, or pointers, to one set of records in another; the speed and versatility of network databases have led to their wide use in business. Relational databases are used where associations among files or records cannot be expressed by links; a simple flat list becomes one table, or “relation”, and multiple relations can be mathematically associated to yield desired information. Object-oriented databases store and manipulate more complex data structure s, called “objects”, which are organized into hierarchical classes that may inherit properties from classes higher in the chain; this database structure is the most flexible and adaptable.The information in many databases consists of natural-language texts of documents; number-oriented database primarily contain information such as statistics, tables, financial data, and raw scientific and technical data. Small databases can be maintained on personal-computer systems and may be used by individuals at home. These and larger databases have become increasingly important in business life. Typical commercial applications include airline reservations, production management, medical records in hospitals, and legal records of insurance companies. The largest databases are usually maintained by governmental agencies, business organizations, and universities. These databases may contain texts of such materials as catalogs of various kinds. Reference databases contain bibliographies or indexes that serve as guides to the location of information in books, periodicals, and other publishedliterature. Thousands of these publicly accessible databases now exist, covering topics ranging from law, medicine, and engineering to news and current events, games, classified advertisements, and instructional courses. Professionals such as scientists, doctors, lawyers, financial analysts, stockbrokers, and researchers of all types increasingly rely on these databases for quick, selective access to large volumes of information.DBMS Structuring TechniquesSequential, direct, and other file processing approaches are used to organize and structure data in single files. But a DBMS is able to integrate data elements from several files to answer specific user inquiries for information. That is, the DBMS is able to structure and tie together the logically related data from several large files.Logical Structures. Identifying these logical relationships is a job of the data administrator. A data definition language is used for this purpose. The DBMS may then employ one of the following logical structuring techniques during storage access, and retrieval operations.List structures. In this logical approach, records are linked together by the use of pointers. A pointer is a data item in one record that identifies the storage location of another logically related record. Records in a customer master file, for example, will contain the name and address of each customer, and each record in this file is identified by an account number. During an accounting period, a customer may buy a number of items on different days. Thus, the company may maintain an invoice file to reflect these transactions. A list structure could be used in this situation to show the unpaid invoices at any given time. Each record in the customer in the invoice file. This invoice record, in turn, would be linked to later invoices for the customer. The last invoice in the chain would be identified by the use of a special character as a pointer.Hierarchical (tree) structures. In this logical approach, data units are structured in multiple levels that graphically resemble an “upside down” tree with the root at the top and the branches formed below. There’s a superior-subordinate relationship in a hierarchical (tree) structure. Below the single-root data component are subordinateelements or nodes, each of which, in turn, “own” one or more other elements (or none). Each element or branch in this structure below the root has only a single owner. Thus, a customer owns an invoice, and the invoice has subordinate items. The branches in a tree structure are not connected.Network Structures. Unlike the tree approach, which does not permit the connection of branches, the network structure permits the connection of the nodes in a multidirectional manner. Thus, each node may have several owners and may, in turn, own any number of other data units. Data management software permits the extraction of the needed information from such a structure by beginning with any record in a file.Relational structures. A relational structure is made up of many tables. The data are stored in the form of “relations” in these tables. For example, relation tables could be established to link a college course with the instructor of the course, and with the location of the class.To find the name of the instructor and the location of the English class, the course/instructor relation is searched to get the name (“Fitt”), and the course/location relation is a relatively new database structuring approach that’s expected to b e widely implemented in the future.Physical Structures. People visualize or structure data in logical ways for their own purposes. Thus, records R1 and R2 may always be logically linked and processed in sequence in one particular application. However, in a computer system it’s quite possible that these records that are logically contiguous in one application are not physically stored together. Rather, the physical structure of the records in media and hardware may depend not only on the I/O and storage devices and techniques used, but also on the different logical relationships that users may assign to the data found in R1and R2. For example, R1 and R2 may be records of credit customers who have shipments send to the same block in the same city every 2 weeks. From the shipping department manager’s perspective, then, R1 and R2 are sequential entries on a geographically organized shipping report. But in the A/R application, the customers represented by R1 and R2 may be identified, and their accounts may be processed,according to their account numbers which are widely separated. In short, then, the physical location of the stored records in many computer-based information systems is invisible to users.。
外文翻译ASP简介
附件1：外文资料翻译译文ASP简介服务器端的方案设计曾经相当的困难。
如果想要通过CGI书写代码就必须要求掌握一些编程语言，例如Perl或是C语言，然后导入，这样的工作效率是非常低的。
之后有人改进了CGI技术，一种新的运用于服务器端的程序产生了。
如果你的源程序是用Perl等解释程序编写的，服务器程序就需要运行一个Perl的解释程序，这样会占据处理器许多的时间和内存空间。
这种情况如果在那些每天采集一千多数据的站点后果是十分严重的。
同样，你也不可能给程序划分出一个完美的分界面，就象VB、VC++、或者其他一些程序。
你可以通过观察它们的运行时所产生的错误，去检验该程序的运行代码。
这是一种对于枯燥乏味的寻找语法错误的很有趣的实践体验，然而，在此之前必须通过学习认识到在生命中有更好的事情需要做，例如阅读WiredNew.微软努力尝试去通过他们所开发的ASP技术去改变以上的那些情况。
ASP技术是由服务器产生的页面去指导其他程序执行一些操作，例如access databases（按日计工资存取），提供不同页面给不同的基础浏览器，现在我们已经很少使用以前的服务器程序CGI，ASP就如同是一个高效率的提供给服务器直接运行编码的解释程序，并且ASP的工作效率要比CGI高的多，因为ASP主要运行于服务性工作，并且使用多线程体系结构保持优势。
这里是来自Microsoft site的一段解释：“ASP是一个公开的、编译快捷的应用程序环境，在这里你可以结合HTML、源程序、并且可以再度使用ActiveX服务构造来创建动态的，强有力的基于Web的商业解决方案。
ASP能够提供服务器端程序通过自带的IIS，并且支持VBScript和Jscript两种脚本语言。
”听起来很棒，是吗？但是，要紧记的是ASP并不是治疗癌症的完美的药方。
的确，他可以治愈你的烦恼如果你是一个拥有老资质的微软开发者，舒适的伫立在垄断地位。
IMNSHO，ASP的提出以致于世界上所有的VB程序将再次被需要。
毕业设计(外文翻译)--开发一个ASP网站所运用的工具
外文翻译沈阳航空工业学院北方科技学院2008年7月ASP development of a site by the use of tools 1. Dream weaverMacromedia Dream weaver is a professional HTML editor for visually designing and managing web sites and pages. Whether you enjoy the control of hand-coding HTML or prefer to work in a visual editing environment, Dream weaver makes it easy to get started and provides you with helpful tools to enhance your Web design experience.Dream weaver includes many coding tools and features: an HTML, CSS, and JavaScript reference, a JavaScript debugger, and code editors (the Code view and Code inspector) that allow you to edit JavaScript, XML technology imports HTML documents without reformatting Macromedia’s Roundtrip HTML technology imports HTML documents without reformatting the code and you can set Dream weaver to clean up and reformat HTML when you want it to .Dream weaver’s visual editing features also let you quickly add design and functionality to your pages without writing a line of code. You can view all your site elements or assets and drag them from an easy-to-use panel directly into a document. Streamline your development workflow by creating and editing images in Macromedia Fireworks, then importing them directly into Dream weaver, or by adding Flash objects you create directly in Dream weaver.Dream weaver is fully customizable. Use Dream weaver to create your own objects and commands, modify keyboard shortcuts, and even write JavaScript code to extend Dream weaver’s capabilities with new behaviors, property inspectors and site reports.The Dream weaver work areaLet’s start with a brief overview of the Dream weaver work area.If you haven’t already launch Dream weaver, double-click the Dream weaver icon to launch it.The Dream weaver work area accommodates different styles of working and levels of expertise.When you launch Dream weaver, the following work area items open:The Document window displays the current document as you create and edit it.The Objects panel contains icons you click to insert objects in you document.Dream weaver provides many floating panels, such as the HTML Styles panel and the code inspector which enable you to work with other Dream weaver elements.The Launcher bar contains buttons for opening and closing your most frequently used inspectors and panels.The Property inspector displays properties for the selected object or text, and lets you modify those properties.(Which properties appear in the inspector depend on the object actively selected in the document.)To open Dream weaver’s windows, inspectors and panels, use the Window menu. A check mark next to an item in the Window menu indicates that the named item is currently open(though it may be hidden beh ind other windows). To display an item that isn’t currently open, choose the item name from the menu or use its keyboard shortcut.Working in Dream weaverDream weaver can display a document in three ways: in Design view, in Code view, and in a split view that shows both the design and code.(To change the view in which you’re working ,select a view in the Dream weaver toolbar.)By default, Dream weaver displays the document window in design view.In addition, you can work with Dream weaver’s design view in t wo different ways in layout view and standard view.( You select these views in the view category of the objects panel.) In layout view you can design a page layout. Insert graphics, text, and other media; in standard view, in addition to inserting graphics text and media, you can also insert layers, create frame documents, create tables, and apply other changes to your page-options that aren’t available in layout view.2.databaseYou know that a database is a collection of logically related data elements that maybe structured in various ways to meet the multiple processing and retrieval needs of organizations and individuals. There’s nothing new about databases-early ones were chiseled in stone, penned on scrolls, and written on index cards. But now databases are commonly recorded on magnetically media, and computer programs are required to perform the necessary storage and retrieval operations.You’ll see in the following pages that complex data relationships and linkages maybe found in all but the simplest databases. The system software package that handles thedifficult tasks associated with creating, accessing, and maintaining database records is called a database management system(DBMS).The programs in a DBMS package establish an interface between the database itself and the users of the database.(These users may be applications programmers, managers and others with information needs, and various OS programs.)A DBMS can organize, process, and present selected data elements from the database. This capability enables decision makers to search, probe, and query database contents in order to extract answers to nonrecurring and unplanned questions that aren’t available in regular reports.These questions might initially be vague and/or poorly defined, but people can “browse” through the database until they needed information. In short, the DBMS will “manage” the stored data items and assemble the needed items from the common database in response to the queries of those who aren’t programmers. Ina file-oriented system, users needing special information may communicate their needs to programmer, who, when time permits, will write one or more prepare the information.The availability of a DBMS, however, offers users a much faster alternative communications path.3. SQL AND SQL SERVERIBM invented a computer language back in the 1970s designed specifically for database queries called SEQUEL; those letters stand for Structured English QUERY for queries, but can also build databases and manage the database engine’s secu rity. Because of this heritage you can pronounce it “sequel” or spell it out “S-Q-L.” There are various versions of SQL used in today’s database engines. Microsoft SQL Server uses a version called Transact-SQL, or T-SQL, which stands for Transaction SQL.⑴What Is SQL Server?SQL Server is a client/server relational database management system (RDBMS)that use Transact-SQL to send requests between a client an SQL Server.⑵Client/Server ArchitectureThe terms client, server, and client/server can be used to refer to very general concepts or to specific items of hardware or software. At the most general level, a client is any component of a system that requests services or resources from other components of asystem. A server is any component of a system that provides services or resources to other components of a system.For example, when you print a document from your workstation on a network, the workstation is the client and the machine that does the print spooling is the server.Any client/server data-base system consists of the following components:The server—A collection of data items and supporting objects organized and presented to facilitate services, such as searching ,sorting , recombining ,retrieving, updating ,and analyzing data.. The database consists of the physical storage of data and the data base services. All data access occurs through the server; the physical data is never accessed directly by the client.The client—A software program that might be used interactively by a person or that could be an automated process. This includes all software that interacts with the server, either requesting data from or sending data to the database.The communication between the client and the server---- The communication between the client and the server depends largely on how the client and server are implemented. Both physical and logical layers of communication can be identified.When you communicate with someone using the telephone, the telephone system is the physical layer and a spoken natural language is the logical layer of communication. For a data-based system, the physical layer can be a network if the server and the client are on different computers. It can be intercrosses communication if the server and the client are on the same computer. The logical communication structure of the physical layer may be low-level operating system calls, a proprietary data access language, or the open structured query language (SQL)4. IISInternet Information Server is the acronym (IIS) is a World Wide Web server. Gopher server and FTP server all inclusive inside. IIS means that you can publish web pages, and there are ASP (Active Server Pages), JAVA, VBscript generated pages, with some extensions. IIS support some interesting things, like the editorial environment interface (FRONTPAGE), a full-text search function (INDEX SERVER), a multimedia capabilities (NET SHOW)Secondly, IIS is with Windows NT Server 4.0 to provide the documents and application server, Windows NT Server is built on the basic Internet server components. Windows NT Server and its fully integrated, allowing the use of Windows NT Server built-in security, and the NTFS file system build a powerful and flexible Internet / Intranet site.IIS (Internet Information Server, Internet Information Services) is a Web (Web) services components, including Web server, FTP server, NNTP server and the SMTP server, were used for web browsing, file transfer, mail and news services and so on It makes the network (including the Internet and LAN) on the release of information has become a very easy matter.IIS is the abbreviation for Internet Information Server, Microsoft is pushing the main server, the latest version is included Windows2000 inside the IIS 5, IIS and WindowNT Server fully integrated together, so users can use Windows NT Server and NTFS (NT File System , NT file system) built-in security features, building a strong, flexible and secure Internet and Intranet sites.IIS support HTTP (Hypertext Transfer Protocol, Hypertext Transfer Protocol), FTP (File Transfer Protocol, file transfer protocol) and SMTP protocol, through the use of CGI and ISAPI, IIS can be a high degree of expansion.IIS support has nothing to do with the language of the script preparation and components, through the IIS, developers can develop a new generation of dynamic, full of charm of the Web site. IIS does not require developers to learn new scripting language or compiler applications, IIS full support for VBScript, JScript software development and Java, it also supports the CGI and WinCGI, and the expansion and ISAPI filter.IIS is designed to establish a set of integrated server services to support HTTP, FTP and SMTP, it can provide quick and integration of existing products, while expansion of the Internet server.IIS highly relevant, while the consumption of system resources is at least, IIS installation, configuration and management are very simple, it is because IIS and Windows NT Server network operating system closely integrated with the other, IIS also use the Windows NT Server the same as the SAM (Security Accounts Manager, Security Account Manager), the administrators, IIS, such as the use of Performance Monitor and SNMP (Simple Nerwork Management Protocol, SNMP) such as the NT has management tools.IIS support for ISAPI, ISAPI to expand the use of server functions, and the use of ISAPI filter can be pre-treatment and post-processing stored in the IIS on the data. For 32-bit Windows applications can be extended to the Internet FTP, SMTP and HTTP-placed and easy to use task focus of the interface, the interface will be the use of Internet applications greatly simplified, IIS also supports MIME (Multipurpose Internet Mail Extensions, More for Internet Mail Extensions), it can access the Internet applications provide a simple registration of.IIS is an important characteristic to support ASP. IIS 3.0 version after the introduction of the ASP, can easily display dynamic content and the development of Web-based applications. For such as VBScript, JScript development of software, or from Visual Basic, Java, Visual C + + development system, and the existing WinCGI CGI scripts and applications developed, IIS provide strong local support.开发一个ASP网站所运用的工具1.

计算机专业B-S模式 ASP 外文翻译外文文献英文文献中英对照外文翻译ENGLISHE:Develop Web application program using ASP the architecture that must first establish Web application. Now in application frequently with to have two: The architecture of C/S and the architecture of B/S.Client/server and customer end / server hold the architecture of C/S.The customer / server structure of two floor.Customer / server ( Client/Server ) model is a kind of good software architecture, it is the one of best application pattern of network. From technology, see that it is a logic concept, denote will a application many tasks of decomposing difference carry out , common completion is entire to apply the function of task. On each network main computer of web site, resource ( hardware, software and data ) divide into step, is not balanced, under customer / server structure, without the client computer of resource through sending request to the server that has resource , get resource request, so meet the resource distribution in network not balancedness. With this kind of structure, can synthesize various computers to cooperate with work, let it each can, realize the scale for the system of computer optimization ( Rightsizing ) with scale reduce to melt ( Downsizing ). Picture is as follows:It is most of to divide into computer network application into two, in which the resource and function that part supports many users to share , it is realized by server; Another part faces every user , is realized by client computer, also namely, client computer is usual to carry out proscenium function , realizes man-machine interaction through user interface , or is the application program of specific conducted user. And server usually carries out the function of backstagesupporter , manages the outside request concerning seting up, accepting and replying user that shared. For a computer, it can have double function , is being certain and momentary to carve to act as server , and again becomes client computer in another time.Customer / server type computer divide into two kinds, one side who offers service is called as server , asks one side of service to be called as customer. To be able to offer service, server one side must have certain hardware and corresponding server software; Also, customer one side must1also have certain hardware and corresponding customer software.There must be a agreement between server and customer, both sides communicate according to this agreement.Apply customer / server model in Internet service , the relation between customer and server is not immutable. Some Internet node offers service on the one hand , also gets service on the other hand from other node; It is even in one time dialogue course, mutual role also exchanges probably. As in carry out file transmission , if be called as one side who offers file server, is called as one side who gets file customer, when using get or mget order since another node takes file, can think that what self use and it is client computer , is using put or mput order to another node dispatch file can again think the machine that used self is server.Multilayer customer / server structureAlong with the development of enterprise application, recently, have again arisen a kind of new multilayer architecture, it applies customer end to divide into two minutes: Customer application and server apply. Customer application is the part of original customer application , is another and partial to have been transfered to server to apply. New customer application takes the responsibility for user interface and simple regular business logic and new server application resident core , changeable business logic. Therefore its structure has become new( Client application + Server application )/Server structure. Following picture shows:This kind of structure has solved traditional Client/Server can expand problem, have reduced customer end business logic , and have reduced the requirement of customer end for hardware. At the same time because of a lot of business logic concentrations have gone to unitary application server on, the maintenance work of application system had been also concentrated together, have eliminated the problem in the traditional structure of Client/Server that software distributes. This kind of structure is called as the architecture of B/S.Browser/Server and browser / server hold the architecture of B/S. On2essence, Browser/Server is also a kind of structure of Client/Server, it is a kind of from the traditional two levels of structural development of Client/Server come to the three-layer structural special case of Client/Server that applied on Web.In the system of Browser/Server, user can pass through browser to alot of servers that spread on network to send request. The structure of Browser/Server is maximum to have simplified the work of client computer, on client computer, need to install and deploy few customer end softwareonly , server will bear more work, for database visit and apply program carry out will in server finish.Under the three-layer architecture of Browser/Server, express layer ( Presentatioon ) , function layer ( Business Logic ) , data layer( Data Service ) have been cut the unit of 3 relative independences: It is the first layer of to express layer: Web browser.In expressing layer contain system show logic, locate in customer end. It's task is to suggest by Web browser to the certain a Web server on network that service is asked , after verifying for user identity, Web server delivers needed homepage with HTTP agreement to customer end, client computer accept the homepage file that passed , and show it in Web browser on.Second layer function layer: Have the Web server of the application function of program extension.In function layer contain the systematic handling of general affairs logic, locate in Web server end. It's task is the request concerning accepting user , need to be first conducted and corresponding to expand application program and database to carry out connection , passes through the waies such as SQL to database server to put forward data handling to apply for, then etc. database server the result of handling data submit to Web server, deliver again by Web server to return customer end.The number of plies of 3th according to layer: Database server.In data layer contain systematic data handling logic, locate in database server end. It's task is to accept the request that Web server controls for database, realization is inquired and modified fordatabase , update etc. function, submit operation result to Web server.Careful analysis is been easy to see , the architecture ofBrowser/Server of three-layer is the handling of general affairs of the two levels of structure of Client/Server logic modular from the task of client computer in split , from the first floor of individualcomposition bear the pressure of its task and such client computer have alleviated greatly, distribute load balancedly and have given Web server, so from the structural change of Client/server of original two floor the structure of Browser/Server of three-layer. This kind of three-layer architecture following picture shows.This kind of structure not only client computer from heavy burdenand3the requirement of performance that rises continuously for it in liberation come out , also defend technology people from heavy maintenance upgrading work in free oneself. Since client computerhandles general affairs , logic partial minutes have given function server, make client computer right off " slender " a lot of, do not take the responsibility for handling complex calculation and data again visit etc. crucial general affairs, is responsible to show part, so, maintenance people do not rush about again for the maintenance work ofprogram between every client computer, and put major energy in the program on function server update work. Between this kind of three-layer structural layer and layer, the mutually independent change of any first floor does not affect the function of other layer. It has changed the defect of the two levels of architecture of Client/Server of tradition from foundation, it is the transform with deep once in application systematic architecture.The contrast of two architecturesThe architecture of Browser/Server and the architecture ofClient/Server compare with all advantages that not only have the architecture of Client/Server and also have the architecture ofClinet/Server the unique advantage that place does not have: Open standard: The standard adopted by Client/Server only in department unification for but, it's application is often for special purpose.It is lower to develop and defend cost: It need to be implemented on all client computers that the application of Client/Server must develop the customer end software for special purpose, no matter installation and disposition escalate still, have wasted manpower and material resources maximumly. The application of Browser/Server need in customer end have general browser , defend and escalate to work in server end go on , need not carry out any change as customer holds , have reduced the cost of development and maintenance so greatly.It is simple to use , interface friendly: The interface of the userof Client/Server is decided by customer end software, interface and the method of its use are not identical each, per popularize a system of Client/Server ask user study from the beginning, is hard to use. The interface of the user of Browser/Server is unified on browser, browseris easy to use , interface friendly, must not study use again other software, the use of a Lao Yong Yi that has solved user problem.Customer end detumescence: The customer end of Client/Server has the function that shows and handles data , as the requirement of customerend is a client computer " it is fat " very high. The customer of Browser/Server holds the access that not takes the responsibility for database again and the etc. task of complex data calculation, need it only show , the powerful role that has played server fully is so largeto have reduced the requirement for customer end, customer end become very " thin ".4System is flexible: The 3 minutes of the system of Client/Server, in modular, have the part that need to change to want relation to the change of other modular, make system very difficult upgrading. The 3 minutes of the system of Browser/Server modular relative independence,in which a part of modular change, other modular does not get influence, it is very easy that system improve to become, and can form the system with much better performance with the product of different manufacturer.Ensure systematic safety: In the system of Client/Server, directlyjoin with database server because of client computer, user can veryeasily change the data on server, can not guarantee systematic safety. The system of Browser/Server has increased a level of Web server between client computer and database server , makes two not to be directlylinked again, client computer can not be directly controled for database, prevent user efficiently invade illegally.The architecture of Browser/Server of three-layer has the advantage that a lot of traditional architectures of Client/Server does not have , and is close to have combined the technology of Internet/Intranet, isthat the tendency of technical development tends to , it application system tape into one brand-new develop times. From this us option the configuration of B/S the architecture that develops as system.what are C/S with B/SFor " C/S " with the technology of " B/S " develop change know ,first,must make it clear that 3 problems.( 1 ) What is the structure of C/S.C/S ( Client/Server ) structure, the server structure and client computer that all know well. It is software systematic architecture, through it can hold hardware environment fully using two advantage, realize task reasonable distribution to Client end and Server end , have reduced systematic communication expense. Now, the most systems of application software are the two levels of structure of the form ofClient/Server , are developing to the Web application of distributiontype since current software application is systematic, Web and the application of Client/Server can carry out same business handling , apply different modular to share logic assembly; Therefore it is systematic that built-in and external user can visit new and existing application , through the logic in existing application system, can expand new application system. This is also present application system develop direction. Traditional C , S architecture though adopting is open pattern, but this is the openness that system develops a level , in specific application no matter Client end or5Server end the software that need to still specify support. Because of the software software that need to develop different edition according to the different system of operating system that can not offer the structure of C/S and the open environment of user genuine expectation , besides, the renovation of product is very rapid, is nearly impossible to already meet the 100 computer above users of local area network at the same time use. Price has low efficiency high. If my courtyard uses , Shanghai exceed the orchid company's management software " statistics of law case" is typical C , Sarchitecture management software.( 2 ) What is the structure of B/S.B/S ( Browser/Server ) structure browser and server structure. It is along with the technology of Internet spring up , it is for thestructure of improvement or a kind of change of the structure of C/S.Under this kind of structure, user working interface is to realize through WWW browser, lose the logic of general affairs very much infront( Browser) realization, but the major logic of general affairs in server end( Server) realization, form the three-layer claimed 3-tier structure. So, have simplified customer end computer load greatly , have alleviated system to defend workload and the cost with upgrading , have reduced the overall cost of user ( TCO ). With present technology see , local area network the network application that establishes thestructure of B/S , and under the pattern of Internet/Intranet, database application is easy to hold relatively , cost also is lower. It is that oneness goes to the development of position , can realize different people, never same place, with difference receive the way of entering ( for example LAN, WAN, Internet/Intranet etc.) visit and operate common database; It can protect data platform efficiently with management visit limits of authority, server database is also safe. Now in my courtyard, net ( Intranet ) , outer net ( Internet ) with Beijing eastern clear big company " law case and the management software of official business " is the structural management software of B/S , policemen each workingstation in local area network pass through WWW browser can realize working business. Especially in JAVA step platform language appearance after, the configuration management software of B/S is more facilitated , is shortcut, efficient.( 3 ) The management software technology of main stream.6The technology of main stream of management software technology isas management thought , have also gone through 3 develop period. First, interface technology goes to Windows graph interface ( or graph user interface GUI ) from last century DOS character interface, till Browser browser interface 3 differences develop period. Secondly, today own the browser interface of computer, is not only visual and is easy to use , what is more major is that any its style of application software based on browser platform is as, make the requirement of choosing a person for the job for operating training not high and software operability is strong , is easy to distinguish; Moreover platform architecture the file that also goes to today from past single user development , server ( F , S ) system and client computer , server ( C , S )system and browser , server ( B , S ) system.The comparison of C/S and B/SC/S and B/S is the now world two technologies of main stream ofdeveloping pattern technical configuration. C/S is that American Borland company researches and develop most early, B/S is that American Microsoft researches and develop. Now this two technologies with quilt world countries grasp , it is many that domestic company produce article with C/S and the technical development of B/S. This two technologies have the certain market share of self , is with customer crowd , each domestic enterprise says that own management software configuration technical function is powerful, advanced, convenient , the customer group that can lift , have a crowd scholar ink guest to shake flag selfcry out , advertisement flies all over the sky , may be called benevolent to see kernel, sage sees wisdomC/S configures inferior position and the advantage of software( 1 ) Application server operation data load is lightcomparatively.The database application of the most simple architecture of C/S is become by two partial groups, customer applies program and database server program. Both can be called as proscenium program and the program of backstage supporter respectively. The machine of operation database server program is also called as application server. Once server program had been started , waits the request concerning responding customer program hair at any time; Customer application program operation can be7called as customer computer on the own computer of user, in correspondence with database server, when needs carry out any operation for the data in database, customer program seeks server program voluntarily , and sends request to it, server program is regular as basis intends to make to reply, send to return result, application server operation data load is lighter.( 2 ) Data store management function relatively transparent.In database application data store management function, is carried out respectively independently by server program and customerapplication program , is regular as proscenium application can violate , and usually those different( no matter is have known still unknown )operations data, in server program, do not concentrate realization, for instance visit limits of authority, serial number can be repeated , must have customer talent establishment the rule order. It is these to own , for the last user that works on proscenium program is " transparent ", they need not be interest in ( can not usually also interfere ) the course of behind, can complete own all work. In the application of customer server configuration proscenium program not is very " thin ", troublesome matter is delivered to server and network. In the system of C/S take off , database can not become public really , professionally more competent storehouse, it gets independent special management.( 3 ) The inferior position of the configuration of C/S is high maintenance cost make investment just big.First, with the configuration of C/S, will select proper database platform to realize the genuine "unification" of database data, make the data synchronism that spreads in two lands complete deliver by database system go to manage, but the logically two operators of land will directly visit a same database to realize efficiently , have so some problems, if needs establishment the data synchronism of " real time ", the database server that must establish real time communication connection between two places and maintains two lands is online to run , network management staff will again want to defend and manage for customer end as server defends management , maintenance and complex tech support and the investment of this high needs have very high cost, maintenance task is measured.Secondly, the software of the structure of C/S of tradition need to develop the8software of different edition according to the different system of operating system , is very rapid because of the renovation of product, price is working needs high with inefficient already do not meet. In JAVA step platform language appearance after, the configuration of B/Sis more vigorous impact C/S , and forms threat and challenge for it. .The advantage of B/S configuration software( 1 ) The Maintenance of inferior position and upgrading way are simple. Now upgrading and the improvement of software system more and more frequently, the product of the configuration of B/S embodies more convenient property obviously. For one a little a little bit big unit , if systematic administrator needs , between hundreds of 1000 even last computers round trip run , efficiency and workload is to can imagine,but the configuration of B/S software needs management server have been all right , all customer ends are browser only, need not do any maintenance at all. No matter the scale of user has , is what , has how many branch will not increase any workload of maintenance upgrading , is all to operate needs to aim at server to go on; If need differently only, net server connection specially , realize long-range maintenance and upgrading and share. So client computer more and more " thin ", and server more and more " fat " is the direction of main stream of future informative development. In the future, software upgrading andmaintenance will be more and more easy , and use can more and more simple, this is for user manpower , material resources, time and cost save is obvious , it is astonishing. Therefore defend and escalate revolutionary way is the client computer " it is thin ", " is fat " server. ( 2 ) Cost reduction, it is more to select.All know windows in the computer of top of a table on nearly one Tong world, browser has become standard disposition, but on server operating system, windows is in absolute dominance position not. Current tendency is the application management software that uses the configuration of B/S all , need to install only in Linux server on , and safety is high. The so server option of operating system is many, no matter choosing those operating system, can let the most of ones use windows in order to the computer of top of a table of operating system does not get influence, this for make most popular free Linux operating system develop fast, Linux except operating9system is free besides, it is also free to link database, this kind of option is very pupular.Say, many persons on daily, "Sina website" nets , so long as having installed browser for can , and what need not know the server of " Sina website " to use is that hat operating system, and in fact the most of websites do not use windows operating wsystem really, but the computer of user is most of as installing to be windows operating system.( 3 ) Application server operation data load value comparatively. Since B/S configures management, software installation in server end ( Server ) on, it is been all right that network administrator need to manage server only, the user interface major logic of general affairs in server ( Server ) end pass through WWW browser completely realization, lose the logic of general affairs very much in front( Browser) realization, all customer ends has only browser, network administrator need to do hardware maintenance only. But application server operation data load is heavier, once occuring " server collapse " to wait for problem, consequence is unimaginable. Therefore a lot of units have database to stock server , are ready for any eventuality.原文翻译:利用ASP开发Web应用程序首先必须确立Web应用的体系结构。

外文翻译Birth of the NetThe Internet has had a relatively brief, but explosive history so far. It grew out of an experiment begun in the 1960's by the U.S. Department of Defense. The DoD wanted to create a computer network that would continue to function in the event of a disaster, such as a nuclear war. If part of the network were damaged or destroyed, the rest of the system still had to work. That network was ARPANET, which linked U.S. scientific and academic researchers. It was the forerunner of today's Internet.In 1985, the National Science Foundation (NSF) created NSFNET, a series of networks for research and education communication. Based on ARPANET protocols, the NSFNET created a national backbone service, provided free to any U.S. research and educational institution. At the same time, regional networks were created to link individual institutions with the national backbone service.NSFNET grew rapidly as people discovered its potential, and as new software applications were created to make access easier. Corporations such as Sprint and MCI began to build their own networks, which they linked to NSFNET. As commercial firms and other regional network providers have taken over the operation of the major Internet arteries, NSF has withdrawn from the backbone business.NSF also coordinated a service called InterNIC, which registered all addresses on the Internet so that data could be routed to the right system. This service has now been taken over by Network Solutions, Inc., in cooperation with NSF.How the Web WorksThe World Wide Web, the graphical portion of the Internet, is the most popular part of the Internet by far. Once you spend time on the Web,you will begin to feel like there is no limit to what you can discover. The Web allows rich and diverse communication by displaying text, graphics, animation, photos, sound and video.So just what is this miraculous creation? The Web physically consists of your personal computer, web browser software, a connection to an Internet service provider, computers called servers that host digital data and routers and switches to direct the flow of information.The Web is known as a client-server system. Your computer is the client; the remote computers that store electronic files are the servers. Here's how it works:Let's say you want to pay a visit to the the Louvre museum website. First you enter the address or URL of the website in your web browser (more about this shortly). Then your browser requests the web page from the web server that hosts the Louvre's site. The Louvre's server sends the data over the Internet to your computer. Your web browser interprets the data, displaying it on your computer screen.The Louvre's website also has links to the sites of other museums, such as the Vatican Museum. When you click your mouse on a link, you access the web server for the Vatican Museum.The "glue" that holds the Web together is called hypertext and hyperlinks. This feature allow electronic files on the Web to be linked so you can easily jump between them. On the Web, you navigate through pages of information based on what interests you at that particular moment, commonly known as browsing or surfing the Net.To access the Web you need web browser software, such as Netscape Navigator or Microsoft Internet Explorer. How does your web browser distinguish between web pages and other files on the Internet? Web pages are written in a computer language called Hypertext Markup Language or HTML.Some Web HistoryThe World Wide Web (WWW) was originally developed in 1990 at CERN, the European Laboratory for Particle Physics. It is now managed by The World Wide Web Consortium, also known as the World Wide Web Initiative.The WWW Consortium is funded by a large number of corporate members, including AT&T, Adobe Systems, Inc., Microsoft Corporation and Sun Microsystems, Inc. Its purpose is to promote the growth of the Web by developing technical specifications and reference software that will be freely available to everyone. The Consortium is run by MIT with INRIA (The French National Institute for Research in Computer Science) acting as European host, in collaboration with CERN.The National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign, was instrumental in the development of early graphical software utilizing the World Wide Web features created by CERN. NCSA focuses on improving the productivity of researchers by providing software for scientific modeling, analysis, and visualization. The World Wide Web was an obvious way to fulfill that mission. NCSA Mosaic, one of the earliest web browsers, was distributed free to the public. It led directly to the phenomenal growth of the World Wide Web.Understanding Web AddressesYou can think of the World Wide Web as a network of electronic files stored on computers all around the world. Hypertext links these resources together. Uniform Resource Locators or URLs are the addresses used to locate thesefiles. The information contained in a URL gives you the ability to jump from one web page to another with just a click of your mouse. When you type a URL into your browser or click on a hypertext link, your browser is sending a request to a remote computer to download a file.What does a typical URL look like? Here are some examples:/The home page for study english.ftp:///pub/A directory of files at MIT* available for downloading.news:rec.gardens.rosesA newsgroup on rose gardening.The first part of a URL (before the two slashes* tells you the type of resource or method of access at that address. For example:∙http - a hypertext document or directory∙gopher - a gopher document or menu∙ftp - a file available for downloading or a directory of such files∙news - a newsgroup∙telnet - a computer system that you can log into over the Internet∙WAIS* - a database or document in a Wide Area Information Search database∙file - a file located on a local drive (your hard drive)The second part is typically the address of the computer where the data or service is located. Additional parts may specify the names of files, the port to connect to, or the text to search for in a database.You can enter the URL of a site by typing it into the Location bar of your web browser, just under the toolbar.Most browsers record URLs that you want to use again, by adding them to a special menu. In Netscape Navigator, it's called Bookmarks. In Microsoft Explorer, it's called Favorites. Once you add a URL to your list, you can return to that web page simply by clicking on the name in your list, instead of retyping the entire URL.Most of the URLs you will be using start with http which stands for Hypertext Transfer Protocol*. http is the method by which HTML files are transferred over the Web. Here are some other important things to know about URLs:∙ A URL usually has no spaces.∙ A URL always uses forward slashes (//).If you enter a URL incorrectly, your browser will not be able to locate the site or resource you want. Should you get an error message or the wrong site, make sure you typed the address correctly.You can find the URL behind any link by passing your mouse cursor over the link. The pointer will turn into a hand and the URL will appear in the browser's status ba r, usually located at the bottom of your screen.Domain NamesWhen you think of the Internet, you probably think of ".com." Just what do those three letters at the end of a World Wide Web address mean?Every computer that hosts data on the Internet has a unique numerical address. For example, the numerical address for the White House is198.137.240.100. But since few people want to remember long strings of numbers, the Domain Name System (DNS)* was developed. DNS, a critical part of the Internet's technical infrastructure*, correlates* a numerical address to a word. To access the White House website, you could type its number into the address box of your web browser. But most people prefer to use "." In this case, the domain name is . In general, the three-letter domain name suffix* is known as a generictop-level domai n and describes the type of organization. In the last few years, the lines have somewhat blurred* between these categories..com - business (commercial).edu - educational.org - non-profit.mil - military.net - network provider.gov - governmentA domain name always has two or more parts separated by dots and typically consists of some form of an organization's name and the three-letter suffix. For example, the domain name for IBM is ""; the United Nations is "."If a domain name is available, and provided it does not infringe* on an existing trademark, anyone can register the name for $35 a year through Network Solutions, Inc., which is authorized to register .com, .net and .org domains. You can use the box below to see if a name is a available. Don't be surprised ifthe .com name you want is already taken, however. Of the over 8 million domain names, 85% are .com domains.ICANN, the Internet Corporation for Assigned Names and Numbers, manages the Domain Name System. As of this writing, there are plans to add additional top-level domains, such as .web and .store. When that will actually happen is anybody's guess.To check for, or register a domain name, type it into the search box.It should take this form: In addition to the generic top-level domains, 244 national top-level domains were established for countries and territories*, for example:.au - Australia.ca - Canada.fr - France.de - Germany.uk - United KingdomFor US $275 per name, you can also register an international domain name with Net Names. Be aware that some countries have restrictions for registering names.If you plan to register your own domain name, whether it's a .com or not, keep these tips in mind:The shorter the name, the better. (But it should reflect your family name, interest or business.)The name should be easy to remember.It should be easy to type without making mistakes.Remember, the Internet is global. Ideally, a domain name will "read" in a language other than English.Telephone lines were designed to carry the human voice, not electronic data from a computer. Modems were invented to convert digital computer signals into a form that allows them to travel over the phone lines. Those are the scratchy sounds you hear from a modem's speaker. A modem on theother end of the line can understand it and convert the sounds back into digital information that the computer can understand. By the way, the word modem stands for MOdulator/DEModulator.Buying and using a modem used to be relatively easy. Not too long ago, almost all modems transferred data at a rate of 2400 Bps (bits per second). Today, modems not only run faster, they are also loaded with features like error control and data compression. So, in addition to converting and interpreting signals, modems also act like traffic cops, monitoring and regulating the flow of information. That way, one computer doesn't send information until the receiving computer is ready for it. Each of these features, modulation, error control, and data compression, requires a separate kind of protocol and that's what some of those terms you see like V.32, V.32bis, V.42bis and MNP5 refer to.If your computer didn't come with an internal modem, consider buying an external one, because it is much easier to install and operate. For example, when your modem gets stuck (not an unusual occurrence), you need to turn it off and on to get it working properly. With an internal modem, that means restarting your computer--a waste of time. With an external modem it's as easy as flipping a switch.Here's a tip for you: in most areas, if you have Call Waiting, you can disable it by inserting *70 in front of the number you dial to connect to the Internet (or any online service). This will prevent an incoming call from accidentally kicking you off the line.This table illustrates the relative difference in data transmission speeds for different types of files. A modem's speed is measured in bits per second (bps). A 14.4 modem sends data at 14,400 bits per second. A 28.8 modem is twice as fast, sending and receiving data at a rate of 28,800 bits per second.Until nearly the end of 1995, the conventional wisdom was that 28.8 Kbps was about the fastest speed you could squeeze out of a regular copper telephoneline. Today, you can buy 33.6 Kbps modems, and modems that are capable of 56 Kbps. The key question for you, is knowing what speed modems your Internet service provider (ISP) has. If your ISP has only 28.8 Kbps modems on its end of the line, you could have the fastest modem in the world, and only be able to connect at 28.8 Kbps. Before you invest in a 33.6 Kbps or a 56 Kbps modem, make sure your ISP supports them.Speed It UpThere are faster ways to transmit data by using an ISDN or leased line. In many parts of the U.S., phone companies are offering home ISDN at less than $30 a month. ISDN requires a so-called ISDN adapter instead of a modem, and a phone line with a special connection that allows it to send and receive digital signals. You have to arrange with your phone company to have this equipment installed. For more about ISDN, visit Dan Kegel's ISDN Page.An ISDN line has a data transfer rate of between 57,600 bits per second and 128,000 bits per second, which is at least double the rate of a 28.8 Kbps modem. Leased lines come in two configurations: T1 and T3. A T1 line offers a data transfer rate of 1.54 million bits per second. Unlike ISDN, a T-1 line is a dedicated connection, meaning that it is permanently connected to the Internet. This is useful for web servers or other computers that need to be connected to the Internet all the time. It is possible to lease only a portion of a T-1 line using one of two systems: fractional T-1 or Frame Relay. You can lease them in blocks ranging from 128 Kbps to 1.5 Mbps. The differences are not worth going into in detail, but fractional T-1 will be more expensive at the slower available speeds and Frame Relay will be slightly more expensive as you approach the full T-1 speed of 1.5 Mbps. A T-3 line is significantly faster, at 45 million bits per second. The backbone of the Internet consists of T-3 lines. Leased lines are very expensive and are generally only used by companies whose business is built around the Internet or need to transfer massiveamounts of data. ISDN, on the other hand, is available in some cities for a very reasonable price. Not all phone companies offer residential ISDN service. Check with your local phone company for availability in your area.Cable ModemsA relatively new development is a device that provides high-speed Internet access via a cable TV network. With speeds of up to 36 Mbps, cable modems can download data in seconds that might take fifty times longer with a dial-up connection. Because it works with your TV cable, it doesn't tie up a telephone line. Best of all, it's always on, so there is no need to connect--no more busy signals! This service is now available in some cities in the United States and Europe.The download times in the table above are relative and are meant to give you a general idea of how long it would take to download different sized files at different connection speeds, under the best of circumstances. Many things can interfere with the speed of your file transfer. These can range from excessive line noise on your telephone line and the speed of the web server from which you are downloading files, to the number of other people who are simultaneously trying to access the same file or other files in the same directory.DSLDSL (Digital Subscriber Line) is another high-speed technology that is becoming increasingly popular. DSL lines are always connected to the Internet, so you don't need to dial-up. Typically, data can be transferred at rates up to 1.544 Mbps downstream and about 128 Kbps upstream over ordinary telephone lines. Since a DSL line carries both voice and data, you don't have to install another phone line. You can use your existing line to establish DSLservice, provided service is available in your area and you are within the specified distance from the telephone company's central switching office.DSL service requires a special modem. Prices for equipment, DSL installation and monthly service can vary considerably, so check with your local phone company and Internet service provider. The good news is that prices are coming down as competition heats up.Anatomy of a Web PageA web page is an electronic document written in a computer language called HTML, short for Hypertext Markup Language. Each web page has a unique address, called a URL* or Uniform Resource Locator, which identifies its location on the network.A website has one or more related web pages, depending on how it's designed. Web pages on a site are linked together through a system of hyperlinks* , enabling you to jump between them by clicking on a link. On the Web, you navigate through pages of information according to your interests.Home Sweet Home PageWhen you browse the World Wide Web you'll see the term home page often. Think of a home page as the starting point of a website. Like the table of contents of a book or magazine, the home page usually provides an overview of what you'll find at the website. A site can have one page, many pages or a few long ones, depending on how it's designed. If there isn't a lot of information, the home page may be the only page. But usually you will find at least a few other pages.Web pages vary wildly in design and content, but most use a traditional magazine format. At the top of the page is a masthead* or banner graphic*, then a list of items, such as articles, often with a brief description. The items in the list usually link to other pages on the website, or to other sites. Sometimes these links are highlighted* words in the body of the text, or are arranged in a list, like an index. They can also be a combination* of both. A web page can also have images that link to other content.How can you tell which text are links? Text links appear in a different color from the rest of the text--typically in blue and underlined. When you move yourcursor over a text link or over a graphic link, it will change from an arrow to a hand. The hypertext words often hint* at what you will link to.When you return to a page with a link you've already visited, the hypertext words will often be in a different color, so you know you've already been there. But you can certainly go there again. Don't be surprised though, if the next time you visit a site, the page looks different and the information has changed. The Web is a dynamic* medium. To encourage visitors to return to a site, some web publishers change pages often. That's what makes browsing the Web so excitingA Home (Page) of Your OwnIn the 60s, people asked about your astrological* sign. In the 90s, they want to know your URL. These days, having a web address is almost as important as a street address. Your website is an electronic meeting place for your family, friends and potentially*, millions of people around the world. Building your digital domain can be easier than you may think. Best of all, you may not have to spend a cent. The Web brims with all kinds of free services, from tools to help you build your site, to free graphics, animation and site hosting. All it takes is some time and creativity.Think of your home page as the starting point of your website. Like the table of contents of a book or magazine, the home page is the front door. Your site can have one or more pages, depending on how you design it. If there isn't a lot of information just yet, your site will most likely have only a home page. But the site is sure to grow over time.While web pages vary dramatically* in their design and content, most use a traditional magazine layout. At the top of the page is a banner graphic. Next comes a greeting and a short description of the site. Pictures, text, and links to other websites follow.If the site has more than one page, there's typically a list of items--similar to an index--often with a brief description. The items in the list link to other pages on the website. Sometimes these links are highlighted words in the body of the text. It can also be a combination of both. Additionally, a web page may have images that link to other content.Before you start building your site, do some planning. Think about whom the site is for and what you want to say. Next, gather up the material that you wantto put on the site: write the copy, scan the photos, design or find the graphics. Draw a rough layout on a sheet of paper.While there are no rules you have to follow, there are a few things to keep in mind:∙Start simply. If you are too ambitious at the beginning, you may never get the site off the ground. You can always add to your site.∙Less is better. Most people don't like to read a lot of text online. Break it into small chunks.∙Use restraint. Although you can use wild colors and images for the background of your pages, make sure your visitors will be able to readthe text easily.∙Smaller is better. Most people connect to the Internet with a modem.Since it can take a long time to download large image files, keep the file sizes small.∙Have the rights. Don't put any material on your site unless you are sure you can do it legally. Read Learn the Net's copyright article for moreabout this.Stake Your ClaimNow it's time to roll up your sleeves and start building. Learn the Net Communities provides tools to help you build your site, free web hosting, and a community of other homesteaders.Your Internet service provider may include free web hosting services with an account, one alternative to consider.Decoding Error MessagesAs you surf the Net, you will undoubtedly find that at times you can't access certain websites. Why, you make wonder? Error messages attempt to explain the reason. Unfortunately, these cryptic* messages baffle* most people.We've deciphered* the most common ones you may encounter.400 - Bad RequestProblem: There's something wrong with the address you entered. You may not be authorized* to access the web page, or maybe it no longer exists.Solution: Check the address carefully, especially if the address is long. Make sure that the slashes are correct (they should be forward slashes) and that all the names are properly spelled. Web addresses are case sensitive, socheck that the names are capitalized in your entry as they are in the original reference to the website.401 - UnauthorizedProblem: You can't access a website, because you're not on the guest list, your password is invalid or you have entered your password incorrectly.Solution: If you think you have authorization, try typing your password again. Remember that passwords are case sensitive.403 - ForbiddenProblem: Essentially the same as a 401.Solution: Try entering your password again or move on to another site.404 - Not FoundProblem: Either the web page no longer exists on the server or it is nowhere to be found.Solution: Check the address carefully and try entering it again. You might also see if the site has a search engine and if so, use it to hunt for the document. (It's not uncommon for pages to change their addresses when a website is redesigned.) To get to the home page of the site, delete everything after the domain name and hit the Enter or Return key.503 - Service unavailableProblem: Your Internet service provider (ISP) or your company's Internet connection may be down.Solution: Take a stretch, wait a few minutes and try again. If you still have no luck, phone your ISP or system administrator.Bad file requestProblem: Your web browser may not be able to decipher the online form you want to access. There may also be a technical error in the form.Solution: Consider sending a message to the site's webmaster, providing any technical information you can, such as the browser and version you use.Connection refused by hostProblem: You don't have permission to access the page or your password is incorrect.Solution: Try typing your password again if you think you should have access.Failed DNS lookupProblem: DNS stands for the Domain Name System, which is the system that looks up the name of a website, finds a corresponding number (similar to a phone number), then directs your request to the appropriate web server on theInternet. When the lookup fails, the host server can't be located.Solution: Try clicking on the Reload or Refresh button on your browser toolbar. If this doesn't work, check the address and enter it again. If all else fails, try again later.File contains no dataProblem: The site has no web pages on it.Solution: Check the address and enter it again. If you get the same error message, try again later.Host unavailableProblem: The web server is down.Solution: Try clicking on the Reload or Refresh button. If this doesn't work, try again later.Host unknownProblem: The web server is down, the site may have moved, or you've been disconnected from the Net.Solution: Try clicking on the Reload or Refresh button and check to see that you are still online. If this fails, try using a search engine to find the site. It may have a new address.Network connection refused by the serverProblem: The web server is busy.Solution: Try again in a while.Unable to locate hostProblem: The web server is down or you've been disconnected from the Net.Solution: Try clicking on the Reload or Refresh button and check to see that you are still online.Unable to locate serverProblem: The web server is out-of-business or you may have entered the address incorrectly.Solution: Check the address and try typing it again.Web BrowsersA web browser is the software program you use to access the World Wide Web, the graphical portion of the Internet. The first browser, called NCSA Mosaic, was developed at the National Center for Supercomputing Applications in the early '90s. The easy-to-use point-and-click interface*helped popularize the Web, although few then could imagine the explosive growth that would soon occur.Although many different browsers are available, Microsoft Internet Explorer* and Netscape Navigator* are the two most popular ones. Netscape and Microsoft have put so much money into their browsers that the competition can't keep up. The pitched battle* between the two companies to dominate* the market has lead to continual improvements to the software. Version 4.0 and later releases of either browser are excellent choices. (By the way, both are based on NCSA Mosaic.) You can download Explorer and Navigator for free from each company's website. If you have one browser already, you can test out the other. Also note that there are slight differences between the Windows and MacIntosh* versions.You can surf to your heart's content, but it's easy to get lost in this electronic web. That's where your browser can really help. Browsers come loaded with all sorts of handy features. Fortunately, you can learn the basics in just a few minutes, then take the time to explore the advanced functions.Both Explorer and Navigator have more similarities than differences, so we'll primarily cover those. For the most up-to-date information about the browsers, and a complete tutorial, check the online handbook under the Help menu or go to the websites of the respective* software companies.Browser AnatomyWhen you first launch your web browser, usually by double-clicking on the icon on your desktop, a predefined web page, your home page, will appear. With Netscape Navigator for instance, you will be taken to Netscape's NetCenter.The Toolbar （工具栏）The row of buttons at the top of your web browser, known as the toolbar, helps you travel through the web of possibilities, even keeping track ofwhere you've been. Since the toolbars for Navigator and Explorer differ slightly, we'll first describe what the buttons in common do:o The Back button returns you the previous page you've visited.o Use the Forward button to return to the page you just came from.o Home takes you to whichever home page you've chosen. (If you haven't selected one, it will return you to the default home page,usually the Microsoft or Netscape website.)。

ASP Banner Ad SystemTo the Reader from Joe: This is a user-submitted tutorial by the author above. I have read the tutorial and set the format to fit HTML Goodies, but for the most part have not changed the language. I chose this tutorial because many readers have been asking for more ASP tutorials. This is a great one.Sorry I cannot show you the event here. The HTML Goodies servers do not offer ASP. I will tell you though that if you run IE5.0 or better, open the contents of the zip file into a directory and it runs just fine.If you haven't already, you may want to read my introductory ASP tutorial before this one. If not, then enjoy.There may be a point in your web design career, where your site becomes real popular. That is when companies become interested in advertising on your site. A Banner Ad system can be built to control all those advertisements that you are so willing to display, for a price. Active Server Pages makes it very easy to create a banner ad system. So easy, that the Microsoft ASP developers created an "AdRotator" component for the occasion. Before you begin reading this article, make sure you download the support material below.The files included aread.txtbanner.asp3 banner imagesclicks.aspexample.aspredirect.aspad.txtIn order for the AdRotator component to work, you must configure a text file. This text file contains all the banner ad properties. However, The text file must follow a certain format. The first four lines are as follows：REDIRECT redirect.aspWIDTH 400HEIGHT 50*REDIRECTWhen a banner is clicked, the "AdRotator" component goes to a preliminary page. This page is called a redirect page. The redirect page handles any extra programming events before directing a user to the banners destination. In this example banner system, I called the preliminary file "redirect.asp".WIDTHThis sets the width of the banner ad image. The value must be in pixels.HEIGHTThis sets the height of the banner ad image. The value must be in pixels.*The asterisk tells the "AdRotator" component that it is about to acquire banner ad information. The asterisk is required.Once you define the general properties above the asterisk, then comes the list of banners to display. In the ad.txt file, there are three banners defined below the asterisk.banner1.jpg20banner2.jpg30banner3.jpg30Each banner requires four lines of properties, which follow the format below：Image filenameWeb AddressDescriptionBanner WeightImage FileThe image filename can be a fully qualified web address or relative name that points to the image. If the image is in a different folder, then you also include the folder name as well.(/banner1.jpg, banner1.jpg, or foldername/banner.jpg)>Web AddressThe web address can be a page on your site or a fully qualified web address that leads to another site.DescriptionThe description will be displayed as a tool tip. When you rest your mouse over the banner, the description pops up.Banner WeightThe banner weight determines how much a banner is displayed. The "AdRotator" component adds all of the banner weights and determines theprobability or percent chance of a particular banner being displayed. A banner with a higher weight has better a better probability.NOTE: You can disable a banners property by substituting with a dash. banner3.jpg-30The example entry above would create a banner ad that does not have a web address.Banner.aspThis file uses the "AdRotator" component and analyzes the contents of the ad.txt file. Below is the code.sub banner(strTarget)dim bannerad, htmlset bannerad = server.CreateObject("MSWC.adrotator")bannerad.TargetFrame = strTargethtml = bannerad.GetAdvertisement("ad.txt")Response.Write htmlend subThe first thing to note is that the ASP was written with VBScript. The second thing to note is that the code is written inside a sub procedure called banner(strTarget).For those of you who do not know, a sub procedure allows you to group together a bunch of code that can be reused over and over. Like a function, it takes an argument, such as a word or variable. In the code above the argument is strTarget.Unlike a function, a sub-procedure does not return any values, it just executes the code inside line by line.Inside the sub I declare two variables...dim bannerad, htmlNext I store the "AdRotator" component inside the "bannerad" variable. When storing a component inside a variable you use the set keyword. Since we are programming server-side with ASP, we use server.CreateObject to summon the component. "MSWC.adrotator" is the component key or name value.set bannerad = server.CreateObject("MSWC.adrotator")Next I use a property of the "AdRotator" called "TargetFrame". This property is equivalent to：html = bannerad.GetAdvertisement("ad.txt")Finally, I want to print the contents of the "html" variable. This prints the code that displays the banner images.Response.Write htmlRedirect.aspThis is the file that is processed before someone is redirected to the banners web address. Inside this file, we can capture information like how many times a particular banner is clicked and so on. To start things off, I defined a variable called "strUrl".Dim strUrlNext I store a querystring value inside this new variable.strUrl = Request.Querystring("url")A querystring is nothing more than a bunch of name/value pairs attached to a web address. When a user clicks on a banner, the "AdRotator" component attaches a querystring to the redirect file. So if we were to click banner1.jpg, defined in ad.txt, we would end up with a redirect web address that looks like so.Redirect.asp?url=&image=banner1.jpgIn essence assigning "Request.Querystring("url") to "strUrl", is the same as assigning to it.Finally, I check to see which banner was clicked. I accomplish this with the VBSCript inStr( ) function.if instr(strUrl, "htmlgoodies") thenApplication.Lockapplication("htmlgoodies") = application("htmlgoodies") + 1Application.UnLockResponse.ClearResponse.Redirect strUrlend ifThe inStr( ) function returns the number position of a sub-word (sub-string) within another word (string). The format is as followsInStr(main word, sub-word)If the sub-word exist within the main word, then the function will equal a number greater-than zero or true. If the sub-word does not exist, then the function will equal zero or false. In the example above, I check to see if "htmlgoodies" exist within . Since the answer is true, then the code inside the if... then... statement will execute.Inside the if... then... I use an application variable. An application variable is native to ASP. Application variables store information as long as a web application exist, a web application ceases to exist when say someone shuts off the web hosting server. The beauty of an application variable is that you can define it on one web page and use it in other web pages within your web application. The downfall is that the users computer must have cookies enabled.Anyways, the code adds one to the application variable, every time a banner is clicked. After one is added, the code redirects to the banners web page. So if banner1 was clicked then you shall be redirected to "".Response.Redirect strUrlExample.aspThis is an example page that uses the banner ad system. When you refresh the page, you should most likely see a different banner. Whenever you want to insert the banner ad on a page, you can use the SSI directive below...<!-- #include file="banner.asp" -->Once you include the file above, then you can call the sub-procedure inside the banner.asp file like so...Call banner("_blank")Notice that I supply one of the values for the "TargetFrame" as an argument. So if the banner is clicked, then the web page should open up in a separate browser window.Clicks.aspThis is a very simple page that displays the number of clicks per banner ad. To display the number of times a banner was clicked, you just print the contents of the application variables that were created inside "redirect.asp". Pretty nifty. <% =application("htmlgoodies") %>ASP横幅广告系统乔给读者的话：这是一个由用户提交上述笔者的教程。

Management of traditional news sites in two ways, one static HTML page, update the information needed to re-create the page and then upload the page and modify the corresponding links, the efficiency of this approach is too low because we have little use. The second is based on ASP and scripting languages, dynamic Web pages and databases, through the application of procedures to deal with news, this is way more popular. However, due to the limitations of ASP allows the system itself, there are some insurmountable flaws, and technology has taken on the system performance has been greatly improved, the main performance in the following aspects:

Abstract
The use of ASP and SQL technology news site management system, to achieve the dynamic management of the news Web site, making the management of information more timely, efficient, improve the work efficiency. At the same time, the development of systems theory, systems and design features are introduced.
