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。

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.

ASP NET 5外文文献和翻译
5 : Introducing the 5 PreviewDaniel Roth | Special connect(); issue 2014 shipped as part of the Microsoft .NET Framework 1.0, released in 2002 along with Visual Studio 2002. It was an evolution of Active Server Pages (ASP) that brought object-oriented design, the .NET Base Class Libraries (BCLs), better performance and much more. was designed to make it easy for developers used to writing desktop applications to build Web applications with Web Forms. As the Web evolved, new frameworks were added to : MVC in 2008, Web Pages in 2010, and Web API and SignalR in 2012. Each of these new frameworks built on top of the base from 1.0.With 5, is being reimagined just like ASP was reimagined to in 2002. This reimagining brings many new features:•Full side-by-side support: 5 applications can now be installed on a machine without affecting any other applications on the machine.•Cross-platform support: 5 runs and is supported on Windows, Mac and Linux. •Cloud-ready: Features such as diagnostics, session state, cache and configuration are designed to work locally and in the cloud.•Faster development: The build step is removed; just save source files and refresh the browser and compilation happens automatically.•MVC, Web Pages and Web API: These are all merged together, simplifying the number of concepts.•Flexible hosting: You can now host your entire 5 application on IIS or in your own process.Getting Started with 5 PreviewIn this article, I’ll give an overview of the new experiences the development team—of which I’m a part—has created for 5 and Visual Studio 2015 Preview. For general help with building and running 5 applications, visit /vNext, where you can findstep-by-step guides and additional documentation. In addition, we also post updates regularlyto /b/webdev. To get started, download and install Visual Studio 2015 Preview. Overview of the 5 Runtime 5 has been rebuilt from the ground up to support building modern Web applications and services. It’s open source, cross-platform and works both on-premises and in the cloud. 5 is currently in Preview and under active development on GitHub (/aspnet). I’llprovide an overview of what’s new in the 5 Preview along with pointers to where you can learn more.Flexible, Cross-Platform Runtime At its foundation, 5 is based on a new flexible runtime host. It provides the flexibility to run your application on one of three different runtimes: 1.Microsoft .NET Framework: You can run your 5 applications on the existing .NETFramework. This gives you the greatest level of compatibility for existing binaries. Core: A refactored version of the .NET Framework that ships as a set of NuGet packagesthat you can include with your app. With .NET Core, you get support for true side-by-side versioning and the freedom to use the latest .NET features on your existing infrastructure. Note that not all APIs are available yet on .NET Core, and existing binaries generally need to be recompiled to run on .NET Core.3.Mono: The Mono CLR enables you to develop and run 5 apps on a Mac or Linuxdevice. For mor e information, see the blog post, “Develop vNext Applications on a Mac,” at bit.ly/1AdChNZ.Regardless of which CLR is used, 5 leverages a common infrastructure for hosting the CLR and provides various services to the application. This infrastructure is called the K Runtime Environment (KRE). While it’s somewhat of a mystery where the “K” in KRE comes from (a tribute to the Katana Project? K for Krazy Kool?), the KRE provides everything you need to host and run your app.A New HTTP Pipeline 5 introduces a new modular HTTP request pipeline that can be hosted on the server of your choice. You can host your 5 applications on IIS, on any Open Web Interface for .NET (OWIN)-based server or in your own process. Because you get to pick exactly what middleware runs in the pipeline for your app, you can run with as little or as much functionality as you need and take advantage of bare-metal performance. 5 includes middleware for security, request routing, diagnostics and custom middleware of your own design. For example, here’s a simple middleware implementation for handling of theX-HTTP-Method-Override header:e((context, next) =>{var value = context.Request.Headers["X-HTTP-Method-Override"];if (!string.IsNullOrEmpty(value)){context.Request.Method = value;}return next();}); 5 uses an HTTP pipeline model similar in many ways to the OWIN-based model introduced with Project Katana, but with several notable improvements. Like Katana, 5 supports OWIN, but simplifies development by including a lightweight and easy-to-use HttpContext abstraction.There’s a Package for That Package managers have changed the way developers think about installing, updating and managing dependencies. In 5, all your dependencies are represented as packages. NuGet packages are the unit of reference. 5 makes it easy to build, install and use packages from package feeds and also to work with community packages on the node package manager (NPM) and Bower. 5 introduces a simple JSON format (project.json) for managing NuGet package dependencies and for providing cross-platform build infrastructure. An example project.json file is shown in Figure 1 (a more detailed explanation of each of the supported properties can be found on GitHub atbit.ly/1AIOhK3).Figure 1 An Example project.json File{"webroot": "wwwroot","version": "1.0.0-*","exclude": ["wwwroot"],"packExclude": ["**.kproj","**.user","**.vspscc"],"dependencies": {"Microsoft.AspNet.Server.IIS": "1.0.0-beta1","Microsoft.AspNet.Diagnostics": "1.0.0-beta1"},"frameworks" : {"aspnet50" : { },"aspnetcore50" : { }}}The Best of C# Design-time and run-time compilation for 5 applications are handled using the managed .NET Compiler Platform (code-named “Roslyn”). This means you get to take advantage of the latest C# language features while leveraging in-memory compilation to avoid unnecessary disk I/O. 5 projects are based on a new project system that dynamicallycompiles your application on-the-fly as you’re coding so you can avoid the interruption of a specific build step. This gives you the power of .NET and C# with the agility and feel of an interpreted language.Built-in Dependency Injection All 5 applications have access to a common dependency injection (DI) service that helps simplify composition and testing. All the frameworks built on 5 (MVC, Web API, SignalR and Identity) leverage this common DI service. While 5 comes with a minimalistic Inversion of Control (IoC) container to bootstrap the system, you can easily replace that built-in IoC container with your container of choice.Familiar Web Frameworks 5 includes frameworks for building Web apps and services such as MVC, Web API, Web Pages (coming in a future release), SignalR and Identity. Each of these frameworks has been ported to work on the new HTTP request pipeline and has been built to support running on the .NET Framework, .NET Core or cross-platform.Today, the existing implementations of MVC, Web API and Web Pages share many concepts and duplicate abstractions, but share very little in the way of actual implementation. As part of porting these frameworks to 5, Microsoft decided to take a fresh look at combining these frameworks into a single unified Web stack. MVC 6 takes the best of MVC, Web API and Web Pages and combines it into a single framework for building Web UI and Web APIs. This means from a single controller you can just as easily render a view as return formatted data based on content negotiation.In addition to unification, MVC 6 introduces a host of new features:•Built-in DI support•Ability to create controllers from any class—no base class required•Action-based request dispatching•View Components—a simple replacement for child actions•Routing improvements, including simplified attribute routing•Async views with flush points•Ability to inject servers and helpers into views using @inject•ViewStart inheritance•Tag helpersYou can find more information and samples at /aspnet/mvc.Web Forms isn’t available on 5, but is still fully supported on the .NET Framework. There are a number of important new features coming to Web Forms in the upcoming version of the .NET Framework, including support for HTTP 2.0, async model binding and a Roslyn-based CodeDom provider. We’re also working on various features reminiscent of Web Forms in MVC 6, such as tag helpers and other Razor improvements.Entity FrameworkData is a key part of many applications and Entity Framework (EF) is a popular data access choice for developers. While EF7 isn’t specific to , this new version of EF plays an integral role in 5.EF7 Enables New Platforms EF is widely used in client and server applications that target thefull .NET Framework. A key focus of EF7 is to enable EF to be used on the remaining platforms where .NET development is common. These include 5, Windows Store and Windows Phone applications, as well as .NET-based Mac and Linux applications.For Windows Phone and Windows Store applications, the initial goal is to provide local data access using EF. SQLite is the most common database of choice on devices and will be the primary store for local data on devices with EF7. The full provider model will be available, though, so other data stores can be supported also.EF7 Enables New Data Stores While parts of EF are clearly tied to relational data stores, muchof the functionality that EF provides is also applicable to many non-relational data stores. Examples of such functionality include change tracking, LINQ and unit of work. EF7 will enable providers that target non-relational data stores, such as Microsoft Azure Table Storage.We’re explicitly not trying to build an abstraction layer that hides the type of data store you’re targeting. The common patterns/components that apply to most data stores will be handled by the core framework. Things specific to particular types of data stores will be available asprovider-specific extensions. For example, the concept of a model builder that allows you to configure your model will be part of the core framework. However, the ability to configure things such as cascade delete on a foreign key constraint will be included as extensions in the relational database provider.EF7 Is Lightweight and Extensible EF7 will be a lightweight and extensible version that pulls forward some commonly used features. In add ition, we’ll be able to include some commonly requested features that would’ve been difficult to implement in the EF6 code base, but which can be included from the start in EF7.The team will be keeping the same patterns and concepts you’re used to in EF, except where there’s a compelling reason to change something. You’ll see the same DbContext/DbSet-based API, but it will be built over building block components that are easy to replace or extend as needed—the same pattern used for some of the isolated components added in recent EF releases.More Information on EF7For more information on EF7, visit the “What Is EF7 All About” GitHub page at aka.ms/AboutEF7. The page includes design information, links to blog posts and instructions for trying out EF7. Command-Line ToolsOne of the core 5 tenets was to provide a command-line experience before we built the tooling experience. This means that almost all tasks you need to do with an 5 application can be done from the command line. The main reason for this is to ensure a viable option for using 5 without Visual Studio for those using Mac or Linux machines.KVM The first tool you need to get the full command-line experience for 5 is the K Version Manager (KVM). The KVM command-line tool can download new versions of the KRE and let you switch between them. KRE contains other command-line tools that you might use. How KVM is implemented, and how to get it, depends on the OS. You can download and install KVM for your platform by running the appropriate command from /aspnet/Home.Once you have KVM, you should be able to open a command prompt and run the kvm command. If you run “kvm list,” you’ll see the list of all KRE versions on your machine, as shown in Figure 2.Figure 2 Running “kvm list” at the Command Line to Get a List of KRE Versions on Your MachineIf there are no entries in your list, there are no versions of KRE in your user profile. To fix this, you can run the command “kvm upgrade.” This command will determine the latest version of the KRE available, download it and modify your PATH environment variable so you can use the other command-line tools in the KRE itself.You can use “kvm install <version/latest>” to install a particular version without making it the default. Use the –r switch to indicate whether you want the .NET Core or .NET Frameworkversion of the KRE and the –x86 and –amd64 switches to download the 32- or 64-bit flavors of the KRE. The runtime and bitness switches can be supplied to either install or upgrade.Once you’ve called “kvm upgrade,” you’ll be able to use the K and KPM commands. K can be used to run applications, while KPM is used to manage packages.How does KVM work? At its heart, KVM is just a convenient way to manipulate your PATH. When you use “KVM use <version>,” all it does is change your PATH to the bin folder of the KRE version you specified is on your PATH. By default the KRE is installed by copying and extracting the KRE .zip file into %USERPROFILE%\.kre\packages, so when you type “KVM use 1.0.0-beta1,” KVM will make surethat %USERPROFILE%\.kre\packages\KRE-CLR-x86.1.0.0-beta1\bin is on your PATH.KPM The next tool you’ll want to use is the KRE Package Manager (KPM). The KPM performs two main functions, with a few lesser features:1.You can run “kpm restore” in a folder with a project.json file to download all the packages your application needs.2.It provides the pack command, “kpm pack,” which will take your application and generate aself-contained, runnable image of your application. Here, image means a folder structure that’s designed to be copied to the server and run. It will include all the packages your application requires, as well as, optionally, the KRE on which you want to run the application.The restore command can be run in a folder that contains a project.json file. It will examine thefile and, using NuGet.config, connect to a NuGet feed and attempt to download all the packages your application needs. By default, it will install these packagesin %USERPROFILE%\.kpm\packages so only one copy of any given package needs to be on your dev machine, even if used in multiple projects.Packing your application—by running “kpm pack”—will generate a folder containing everything your app needs to run, including packages, source files and your Web root. You can even optionally include the KRE, although by default it’s assumed the KRE is already on the server.K Command The K command actually runs an 5 application from the command line. The K command is included in the KRE, the same as KPM, and is the entry point to running an application on top of the KRE.The main way to use the K command is to run one of the commands inside your project.json file. Commands are specified by name in the project.json file under the commands property. By default,the 5 Starter Web template includes a “web” command in project.json that hosts your app and listens on port 5000. To run th is command, simply run “k web.”Visual Studio Updates for 5One of the original goals of 5 was to have a great experience for teams in which members use different tools. For example, you can have team members using Windows and Visual Studio working with others who are using Sublime Text on a Mac (see options forcross-platform .NET development tools ). To achieve this, we had to take a step back and rethink Visual Studio support. In previous versions of Visual Studio, the project system assumed that most development was performed in Visual Studio. Visual Studio didn’t work well when other tools were involved to create files or modify the project. For example, in the .csproj file, Visual Studio maintained a list of files that made up the project. If you used a tool to create a new file for your project, you’d then have to edit the .csproj file for it to be included.In Visual Studio 2015, when you create a new 5 project, you get a new experience. You can still develop, debug and run your project as usual, but in addition to the standard features that you’ve come to know in projects, some new features are unique to 5. You now have the freedom to develop using the p latform and tooling of your choice. I’ll discuss some of those features.Support for All Files in the Folder In 5, all files under the project directory are automatically included in the project. You can exclude files from compile or publish in the project.json file. For more info on how to exclude files in project.json, see the GitHub pageat bit.ly/1AIOhK3. After the project is loaded, Visual Studio starts a file watcher and updates Solution Explorer to reflect the changes. Because Solution Explorer is always watching the files under the project directory, we’ve changed the location where generated files will be stored. Instead of storing generated files under the project (bin\ and obj\), we now place generated files by default in a folder named artifacts next to the solution file.Just Edit, Save and Refresh the Browser In existing applications, when you change server-side logic (such as your MVC controller code, or a filter) then you need to rebuild and redeploy the application to see the changes reflected in the browser. Microsoft wanted the Web developer workflow to feel as lightweight and agile as when working with interpreted platforms (such as Node.js or Ruby), while still letting you leverage the power of .NET. In 5 projects, when you edit and save your C# code, a file watcher detects the change and restarts the application. The application is rebuilt in memory, so you can see the results of the change in the browser in near-real time. Not e that this workflow is only supported when you aren’t debugging so as to avoid interrupting your debugging session.Web Publishing In Visual Studio 2015, Microsoft developers are working on a new publish process for 5 projects. In the Preview release, 5 publishing supports publishing to Azure Websites and to the file system (for example, local/network folder). When publishing to Azure Websites, you can select the desired build configuration and KRE version. Later releases will expand this to support a broader set of targets.Migrating to 5Moving existing Web applications to 5 involves both creating a new 5 project for your existing application and then migrating your code and dependencies to run on the new framework. Creating a new 5 project for your application is relatively simple. First, add a project.json file in your project folder. Initially, the project.json file only needs to include an empty JSON object (for example, {}). Next, use File | Open Project to open the project.json file in Visual Studio 2015 Preview. After opening the project.json file, Visual Studio will create an 5 project with a .kproj file and automatically include in the project all the files and directories it finds next to the project.json file. You should see your project files in your new 5 project in the Solution Explorer. You have now created an 5 project for your existing Web application!Migrating your code and dependencies so your new 5 project builds and runs correctly is a more involved process. You need to update your project.json with your top-level package dependencies, framework assembly references and project references. You need to migrate your code to use the new HTTP abstractions, the new middleware model and the new versions of the Web frameworks. You need to move to new infrastructure for handling concerns such as configuration, logging and DI. Porting your application to run on .NET Core requires dealing with additional platform changes and limitations. This is more than can be covered in this article, but we’re working hard to provide complete migration guidance in a future article. While the investment to move to 5 might be significant, Microsoft believes the benefits of providing an open source, community-driven, cross-platform and cloud-ready framework are worth the additional effort.翻译：是微软.NET Framework 1.0运作的一部分，与Visual Studio 2002版本一同发布在2002年。
外文翻译---ASP的开发准则及安全管理
附录外文原文：The exploitation criteria and security management of the asp Exploitation criteria :Application servers have been, or ultimately will be used in Web server, which usually operate in the IIS ASP page computer. ASP is the only object of your client. It offers specialized systems and security considerations. While many of the Web sites use ASP simply not components, but in this article that ASP is the Internet as a bridge between the client and components. The following ASP components Guidelines (English) :ASP and the division of services between componentsASP server in the most commonly used building for the client to use HTML or XML documents, so we focused on the use of the program. This leads to a common problem, if ASP page on the server, then they are part of the operational level? Components in the world, the answer usually is not. Although the ASP server is in operation, but may be related to space applications in the same server, but it can not make it a part of the business logic. With user interface development tool, or as the opening of more business to operational programs with the clear distinction will be tremendous returns.Let us look at some of the most important operational level and that level division guidelines :Separation of the UI code and business logic. This includes preparation coupled with the UI code, such as the use of ASP components MTS internal target it with the business logic code separation, as in a different DLL.affair will be separated with the ASP page. Services ASP in certain cases beyond compare, but the components and multi-storey applications will change this situation. Components should not be dependent on the client layer to manage their affairs and business logic semantics.Will be expressed components (use solicit and responsive components) and Web server on the same machine and / or tenor. If the use of ASP internal components of the target objects on remote machines, then all of the internal components will be available in retail form. Server client access is COM+ server, which significantly reduced the performance and security of complicated. These markings will be lay in COM+ applications mark as "library activated" .ASP exist in server, ASP pages must be consistent with resource sharing rules, andremember to flexibility. Look at the following details :In the "conversation", management should avoid user specific state. Keep ASP stateless and where possible to allow resources pool.Mode operation:In evaluating whether a code of business logic layer or expressed, may I ask myself: "If I have to use click-phone applications to replace my ASP page, then the code are there?</FONT></SPAN></P><P class=MsoNormal style="TEXT-JUSTIFY: inter-ideograph; MARGIN: 0cm0cm0pt; TEXT-ALIGN: justify"><SPAN lang=EN-US><FONT face="Times New Roman" size=3>"If the answer is" yes ", then it could try to business logic code into machine code or user interface to help.If changed after the client code can not be used, or if it is constructed with the help of the user interface, the code is expressed services layer. It ASP page, or in the internal components usedASP components. It does not belong to the operational targets of components. Understanding of the distinction between desktop and ASP clientIt was modular incumbent engine，different table's top' tradition uniline ran win32 application from that asp. Key distinction generalize as follows: Thread management : ASP is a multi-client threads. This means that it can have many activities in the operation, perhaps at the same time dealing with different ASP page. This shows that it is not the only pseudo-objects to exclusive system users. This may be unexpected reactions, for example, into a bad habit : the object stored in ASP application variables or conversation.Security environment : ASP is the Web site of the Internet Information Services 5.0 implementation, a low, medium, high three separate degrees. The Web site can even have different security setup, or refuse to allow anonymous access, for customer and so on. All these have generated a lot of programs, namely, the use of different end-user account is your object.Easy rose : This is not a technical issue, but Web applications provide facilities Deputy effect. Traditionally, the increase in user base for desktop applications, the number of requests carefully planned well known to the client transferred. ASP has changed the process in motion and operational, ASP-Visual Basic applications can be conveniently opened for local or worldwide for all staff, all business partners and customers all use. This approach can be used to describe - owned super links individual e-mail users can make a tenfold increase in the base. To prepare for yourapplications?The only way to understand the intensity of Web sites for testing to obtain the expected value of the actual performance. Detailed information on the intensity of the test, please refer to the "application life cycle" section.In the use of Visual Basic ASP should target? In the context of the establishment and abolition of pages of your audience.In other words, as far as possible so that no state ASP pages only in a state of dependence conversation or temporary applications variables. Not to target storage applications in English or variables. This will lock in your conversation ASP systems, the expected value of flexibility may cancel all. In other words, the Web servers handle no more than a few dozens of users. If required, in English or applications stored content, please turn it into the data rather than objects. There are many other criteria can be observed. We recommend that you read MSDN V oices, .J.D. Meier compose the column "Servin<SPAN style="mso-spacerun: yes"></SPAN>It Up. "The column includes a lot of technology, practice and skills development can contribute to the expansion and reliable ASP components and applications.Not to be quoted or applications memory at conversation all the inserted object components are Visual Basic 6.0 "cell thread", that is to say they are operating in the Inter module. This means that if the thread established targets, then the object of all resources must use the same threads. Many threads (from it Web site users) use the same examples Agency targets, raises a series of activities, the application process may become bottlenecks.In addition, in conversation with Server .Create Object stored within the object STA to be implemented threads can be effectively linked to the current user, thus it will be the largest applications to give users a few restrictions the 20xN (N = number of processors).Mode operation:If you according to our suggest to take object stateless, are not used for storage of a client, and stored in the context of their applications. Client will be able to establish an independent, use and cancellation of their own target. This reduces the need for maintaining conversation - because they do not retain the skills unique to the state. Recommended approach is to target a state, it needs a database or other storage area to visit (such as cookies and LDAP). If applications require the use of English or the scope of the data, the data should instead deal with the subject of data stored in it. The dispose of the you could begin one genera，came encapsulation versus desirable value.ASP security management :The basic concept of security managementSafety management is based on information and ASP solution to manage the security strategy has set the security level definition process. Including management of the response to violations of the security act. ASP can be controlled without fear of attack and ASP clients business continuity, so to be able to deal with malicious attacks could really an art.Safety management in large measure dependent on the security strategy. These strategies could produce from different sources. To be considered when designing security strategy are :Service level agreement on the definition of external customer needs external security law requires external suppliers within the ASP security strategy and security strategy in the ASP environment integrated customer circumstances, the internal / external security strategy, For each solution, ASP must be defined security strategy. The strategy should be based on the various aspects of the most reliable Hop. According to customer needs, and even the basic structure will be very different design. Usually use three safety design:The dedicated network joint of the both asp solution and safety precautions completeness by asp proceed end-to-end Control usually，these purport asp versus proprietary basic structure subassembly possess full control，include asp and client of compartment.Public : ASP solutions and security measures by ASP component control. Usually, this means that within the ASP is in control of its own website, but does not guarantee to provide solutions to the public network with control. However, the ASP can be used as "virtual private network" (VPN) to carry out such technical links between ASP and client security.Mixed : the solution is a combination of the previous two. "dedicated" and "common" solutions are used. In ensuring security solutions, and also involves ASP customers.There are five dimensions of the process needed to improve the MOF model : planning : planning activities including in customer requirements, as well as internal and external strategies based on the legitimate demands of the SLA security component. In a dialogue with clients at the same time, it may be necessary to establish or adjust internal security strategy. Of course we should decide whether to do so by the ASP. This resulted in a level of security planning, including all aspects of the security strategy and design (infrastructure, personnel, steps, the environment, basic contracts, etc.).Implementation : Put stratification plane execute possession necessary safety precautions，withal observe SLA suffer have definitive security part for in force. at a pinch，this phase return should put make ultra internal security policy over in force..Assessment : Assessment is essential to end security management process. It involves determining the strategy and measures adopted by the state and effectiveness.Maintenance : maintenance based on the following security measures on the basis of : the results of regular inspections, the risk of changes in the situation clearly, and SLA or other conditions change.Control : control activities can organize and guide the security management process itself. Definition of a process control activities, functions, roles, responsibilities assigned, organizational structure and reporting structure. It is a continuing process and to ensure the engine improvements.Security management process must be continuous self improvement.

毕业论文外文翻译ASP from A to ZNancy Winnick ClutsDeveloper Technology EngineerMicrosoft CorporationOctober 22, 1998ContentsIntroductionWhat ASP IsHow ASP WorksASP from A to ZBibliographyIntroductionThere's lots of helpful information about Active Server Pages (ASP) available on this site and other sites. If you have plenty of time to search for the information, you can find answers to most of your questions. But if you want to find out what tools you can use to debug ASP or how to handle errors, you need to do some digging. This article provides an easy way to find information that pertains to ASP, including a short definition of what ASP is, how ASP works, and an alphabetical list of terms and tips that relate to ASP. In the A-to-Z list, you will see a brief description as well as pertinent links to more detailed information (when that information is available). This article is meant to be a "living" document. That means that I plan on updating it with new tips and removing tips that no longer apply. If you are an ASP developer and have a "juicy" tip, send it to me. If I publish it here, you'll get credit and the everlasting gratitude of throngs of other ASP developers.What ASP IsActive Server Pages is a programming environment that provides the ability to combine HTML, scripting, and components to create powerful Internet applications that run on your server. If you are already creating Web sites that combine HTML, scripting, and some reusable components, you can use ASP to glue these items together. You can create an HTML interface for your application by adding script commands to your HTML pages and you can encapsulate your business logic into reusable components. These components can be called from script or other components.How ASP WorksWhen you incorporate ASP into your Web site, here's what happens:1.The user brings up a Web site (like MSDN Library) where the default page has the extension .asp.2.The browser requests the ASP file from the Web server.3.The server-side script begins to run with ASP.4.ASP processes the requested file sequentially (top-down), executes any script commands contained in thefile, and produces an HTML Web page.5.The Web page is sent to the browser.Because your script runs on the server, the Web server does all of the processing and standard HTML pages can be generated and sent to the browser. This means that your Web pages are limited only by what your Web server supports. Another benefit of having your script reside on the server is that the user cannot "view source" on the original script and code. Instead, the user sees only the generated HTML as well as non-HTML content, such as XML, on the pages that are being viewed.ASP from A to ZThis section contains a list of terms and tips to help you understand ASP. They are listed in alphabetical order. Scroll down to the topic that interests you or click the letter in the alphabet below to jump down to the section containing the topic. I cribbed, er, I mean, compiled these tips and definitions from a number of sources, including technical articles (listed in the bibliography below), Knowledge Base articles, and a beta version of the Microsoft® Internet Information Server (IIS) 5.0 documentation (I'm so lucky!).A B C D E F G I J L M O P Q R S T V W X ADOActive Data Objects (ADO) provides a programming model for an OLE-DB data source. It is the database model that ASP uses; however, ASP can use other database access mechanisms. ADO supports the following installable objects, which are often used in ASP files: Command, Connection, Recordset, Field, and Error. Refer to the ADO Web site at /data/ado/ for more information than you can shake a stick at.ApplicationsASP is not just for prototyping. When using ASP as a solution, design your solution as an application instead of designing stand-alone ASP pages. As far as objects are concerned, it's best to take a look at what you need to accomplish and decide what you need, then whether you can buy the objects or will need to create the objects yourself. Take into consideration caching, scalability, reusability, security, and consistency.BottlenecksIdentify your bottlenecks (that is, the database, network card, or network connection) using the tools available: WCAT, NetMon, and performance counters. To improve server performance, take a look at all parts of the system for potential bottlenecks, including hardware configuration and software settings. This way, if you are ever asked to scale the project larger, you will know where the work needs to be done.Browser ConnectionIn IIS 4.0, use the Response.IsClientConnected property to determine if the browser is still connected. If the browser is not connected, you can conserve CPU cycles by ceasing the processing of the ASP page. Refer to the Knowledge Base article Use IsClientConnected to Check if Browser is Connected.BufferingTurn buffering ON. By default it is OFF in IIS 4.0; in IIS 5.0, buffering is ON by default. You should buffer your ASP files so that you can abort sending a Web page. This might happen if the script being processed runs into a problem or if a user does not have appropriate security credentials. If this happens, and if you are using IIS 5.0, you can transfer the user to another page using Server.Transfer, or clear the buffer (using the Clear method of the Response object) to send different content to the user.C++If you are creating page-level components, you can use server scriptlets, Visual Basic®, V isual J++™, and VisualC++®. If you are writing components that will be in application or session state, we recommend that you write them in C++ or Java so you can create them as both-threaded. Visual Basic is apartment-threaded. See the section below on threading for more details.CachingIf your application sends pages to the client via a proxy server, the proxy server may cache pages to return them more quickly to the client. This reduces the load on the network and the Web server. To prevent a browser from caching ASP pages, set Response.Expires to some negative number. This will force the cached pages to expire immediately. If you set Response.Expires to 0, and if your browser clock is behind by a few minutes, the page won't expire immediately. If your Web site contains objects that do not expire often, such as images, set the expiration to some time in the future. This will greatly increase the speed at which a page is refreshed or downloaded. Proxy caching via pragma:nocache is already done for you by IIS, so you don't have to set this in your headers. More information about caching can be found in Got Any Cache?Client-Side ScriptsDistribute the work on your Web site by providing script on both the client and the server. See Client-Side and Server-Side Objects.COM Object DebuggingIf you create a COM object and use it through ASP with Server.CreateObject, you cannot go back into your development environment and recompile the COM DLL without restarting the IIS Admin and W3SVC (Web server) service. Otherwise, the COM DLL will be locked. To restart these services, do the following:1.At a command prompt, type net stop iisadmin /y. Please note that this will shut down IIS' parent service,IIS Admin. This will also shut down FTP and other services that are children of IIS Admin. If you type only net stop w3svc, inetinfo.exe will not be unloaded.2.At a command prompt, type net start w3svc. This will restart IIS Admin and the W3SVC service (Webserver).3.You may recompile at any point after Step 1. Once you refer to an object that loads your DLL, you must repeatStep 1 before building the component successfully.ComponentsUse components to encapsulate the business logic in your ASP applications. You can create your own components or buy them "off the shelf." Once you have a component, you can reuse it wherever you need it. Develop your components using C++ or Java. Because Visual Basic is not marked as both-threaded, you cannot use Visual Basic components within application scope. If you design your own components, be sure to design components that are stateless (that is, the methods you define take parameters, rather than having a script set properties then call the method without the parameters).Stateless components are far more flexible and reusable. In addition, if you have areas in your script where you have more than 100 lines of contiguous script, consider turning that script into a server scriptlet. More information about creating components can be found in the Active Server Components section of the Server area of the MSDN Library.A comprehensive list of third-party components available for ASP can be found in the ASP Component Catalog. ConnectionsPool your connections for optimal performance. By pooling your connections, your resources are allocated more efficiently. For support of multiple logons, provide one connection for read-only access and one connection forread/write access. In general, avoid putting ADO connections in session state. ODBC (version 3.0 and later) automatically does connection pooling for you, and OLE-DB provides session pooling.Cookie MungerASP uses cookies to store the session identifier (ASP SessionID). For machines that have cookies turned off, the Cookie Munger tool can be used to strip out cookies and put the information in a URL. This enables the use of "cookies" without actually sending out cookies. For more information, see Simulating Cookies with the Cookie Munger.CPUDesign for scalability. Stress your ASP applications at 100% CPU to determine how to best allocate your resources. Use WCAT or a third-party tool such as Mercury's LoadRunner to tune your performance.Data Access ComponentsRead Improving the Performance of Data Access Components in IIS 4.0 for a detailed explanation of the techniques that you can use to improve performance.DatabaseUse ADO for adding database access to your Web pages via components. ADO can be used to create small components that connect to any OLE-DB compliant data source, whether it's relational or non-relational. This includes spreadsheets, databases, or e-mail directories.DebuggingThere are many tools available for debugging, including the Microsoft Script Debugger. The Script Debugger lets you run your server-side scripts one line at a time, monitor the value of variables, properties, or array elements during execution, and trace procedures.Important:Once you have finished debugging your Web site, don't forget to turn off debuggingon your live servers. This will increase performance.Dictionary ObjectThe Dictionary object enables you to look up and store arbitrary key-data pairs rapidly. The Dictionary object gives you access to items in the array by key, so it is faster to find things that aren't stored contiguously in memory. Instead, you use a key rather than having to know where in the array the object is stored.Disconnected RecordsetsDisconnecting a Recordset means you can view the Recordset's data after severing the connection to the data store that generated the Recordset. You can create a disconnected ADO Recordset in-process with a Recordset whose CursorLocation property is adUseClient and whose ActiveConnection property is set to NULL/Nothing. You can then put the Recordset into ASP application state and use the Recordset Clone method to share and access the Recordset in your ASP files. You can then pass this Recordset to a remote client using either RDS or DCOM (or both together). Read the Knowledge Base articles HOWTO: Getting ADO Disconnected Recordsets in VBA/C++/Java and INFO: Disconnected Recordsets with ADO or RDS for detailed information.Error HandlingYou can use the ASPError object to obtain information about an IIS 5.0 error condition that has occurred in an ASP file. The ASPError object is returned by the Server.GetLastError method. If the error condition generates an exception and you are using VBScript, use OnErr. In JScript™, use the try…catch method. Detailed information about error handling can be found in the article Microsoft JScript Version 5.0 Adds Exception Handling, by Michael Edwards.Flow ControlFlow control is the ability to set the flow of your ASP application. Flow is controlled through Response methods and two new Server methods (for IIS 5.0). Using Response.Redirect causes posted data to be lost. The Response.End method causes ASP to stop when an error is found. You do not need to call this method after callingResponse.Redirect. The Server.Transfer method is the same as Response.Redirect, except that the work is done on the server and posted data is not lost. The Server.Execute method will flow into a nested ASP call and return execution to where you were before the error occurred.FileSystem ObjectThe FileSystem object blocks on files. If you are running a high-volume Web site, don't use the FileSystem object because the performance of accessing a single file will degrade. If you are using multiple files that are not being accessed at the same time, use of the FileSystem object will not result in a performance hit.Global.asaThe Global.asa file is an optional file in which you can specify event procedures and declare objects that have session or application scope. It is not a content file displayed to the users; it stores event information and objects used globally by the application. This file must be named Global.asa and must be stored in the root directory of the application. An application can have only one Global.asa file. Instead of using the ASP FileSystem object to read files on a page, load the file(s) into an Application level array in Global.asa.GlueUse ASP for the glue and components for the business logic. If you have 100 or more lines of consecutive script, turn it into a component using server scriptlets (bearing in mind that server scriptlets have the same limitations as Visual Basic components).InetLoadThe InetLoad tool can be used to tune your Web site. This tool generates customizable loads on various Internet services, over a broad range of Internet protocols, including HTTP, SMTP, POP3, and LDAP. You can use this tool to simulate traffic on your Web site. InetLoad is available at /software/internet/IN00470.htm. See also WCATW and Mercury LoadRunner for tuning tools.InternationalizationIf you are providing a Web site that will be viewed in countries other than the United States, you can use the CODEPAGE tag within the <% %> delimiters to specify the proper code page. Alternatively, you can use the Session.CodePage property. Read all about it at /library/en-us/dnasp/html/nextgen.asp. In addition to CODEPAGE, you can also use the Local Language Identifier (LCID) to determine the language that the user has set as her preference. Detailed information about LCID can be found in the IMultiLanguage Reference.IsolationYou can separate IIS, ASP, and components into different processes for better performance. The drawback to putting these in different processes is the cross-process communication performance hit. You can put IIS, ASP, and your components in one process. This is the fastest method, but if your component goes down, it can bring down ASP and IIS. You can put IIS in one process and ASP with your components in another so that IIS will not crash if your component or ASP crashes. You can put IIS and ASP in one process and your component in another process. This is slower than the previous option due to all of the cross-process communication; however, it does insulate IIS and ASP from a buggy component. The slowest but "safest" option is to put IIS, ASP, and your components all in separate processes. If one crashes, nothing else will, but the performance will be very, very slow. It's a better idea to test your components really well.Component Configuration Protection SpeedIIS, ASP, and components in one process 1 4IIS in one process, ASP and components in another process 2 3IIS and ASP in one process, components in another process 3 2IIS in one process, ASP in one process, components in one process 4 1Legend: 1 = Least, 4 = MostJavaUse Java (or C++) to write components. Java is a powerful language that you can use to create components that are both-threaded.LoggingYou can turn on URI_Query extended logging to log ASP failures. This is not turned on by default. Turning it on is tricky, so here are the steps:1.Select a Web or FTP site and open its property sheets.2.Enable logging if it is disabled and select the W3C Extended log file format.3.Click Properties.4.On the Extended Properties property sheet, select the fields you want to log (in this instance, URI_Query).By default, Time, Client IP Address, Method, URI Stem, and HTTP Status are enabled.5.Click Apply.You can also log to the Windows NT® Server Event Log; however, logging to the Windows NT Server Event Log is not a good idea if you've got lots of errors or are in debugging mode because you can fill up the log quickly. Using the Windows NT Performance Monitor, you can log a variety of error conditions, including how many ASP requests have failed and how many errors occurred during the script run-time.MailUse Collaboration Data Objects (CDO) to send mail for Windows NT Server. CDO is a lightweight version of CDO for Exchange. It works on SMTP or Exchange. If you are using another e-mail protocol, use a third-party component. A comprehensive list is at /workshop/server/components/catalog.asp.<OBJECT> tagIf you need to refer to objects that may not be used, instantiate them by using the <OBJECT> tag rather than using Server.CreateObject. Using Server.CreateObject causes the object to be created immediately. If you don't use that object later, you end up wasting resources.译文内容介绍什么是ASPASP怎样工作图书目录介绍ASP有很多有用的信息被用在这个网站或者其它网站。

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。

这是一个设有一个可配置的字符串缓冲区并且管理新文本插入到该缓冲区，只有当文本长度超过字符串缓冲区的长度时，才产生字符串的充足。
微软网框架免费地提供了这种类别。

毕业设计（论文）外文文献翻译文献、资料中文题目： ASP的发展文献、资料英文题目：文献、资料来源：文献、资料发表（出版）日期：院（部）：专业：班级：姓名：学号：指导教师：翻译日期： 2017.02.14The second，the past ISV (independent software provider ) and VAR (the trader that resells value-added service ), at Internet age , changed the marketing way in the past , would rely mainly on sale of the software product to change direction to rely mainly on the fact that right to use is leased in the past, bale from physics carrier encapsulation way change direction and long-range operation way main fact now, through the cooperation with network operator , realize the transition to ASP；The third ，IT service departments and traditional advisory companies of traditional large- scale organization, at the foundation known deeply in Internet , depend on long-term experience, is it carry on systematic design and implementation of scheme for other customer to begin, through establish in with trader who operates network and alliance relation between the application software manufacturer, realize the ASP provider that appears in the capacity of system integration trader.The second. The developing history and classification of ASP Seen from the present, ASP is as emerging and proposing formally it is only a thing from the end of 1998 to the beginning of 1999 of a kind of mode. And until from the end of 1999 to the beginning of 2000 to a great extent, ASP field relevant outstanding behaviours at the capital market of Company just cause people's extensive concern. In fact speaking from the intension and essence of ASP mode, it is not the brand-new things, but the mode that had once had, has been given the new vitality at Internet age. During this festival, we will review the course that ASP produce development and develop, in order to help the essence of better deep understanding ASP. At the end, we will concentrate on introducing the situation which enterprises divide from different standards in ASP field at present.The third. The development foundation of ASP modeASP as one brand-new concept, proposition and it takes shape to be just time for more than half a year of it, but in U.S.A. and other fast-developing countries of IT industry, ASP is becoming a kind of new developing business mode of leading e-commerce in the future, main maturity based on following IT technology of precondition that ASP produces and develops: Popularization of Internet: Internet deepens people's life progressively , a large number of solutions based on Web are emerging constantly, all these make long-range application scheme based on host computer become possible; The bandwidth is increasing and dropping with the price constantly constantly: Communication performance and bandwidth expenses reduced continuously increased, make the application program at the host computer able to visit through Internet and tight client; Whether client / server can use bysharing under the environment. The remote access in ASP concept , users have already been accustomed to under the enviroment of client / the server, this make remote access and is it is it become acceptable first business mode to use to share; The browser becomes figure interface application program accepting extensively: The wide application and development of the technology of the browser have gathered enough technology and human resources for the calculation based on the calculation of Web and thin client, and good user' s foundation; Potentiality of e-commerce solution: Advanced e-commerce solution, has shared a lot of thorny business and technological question together with concept of ASP, such as systematic security and dependability. So, the enormous motive force of e-commerce is promoting the advancing of ASP. The forth. China ASP market's overviewIn 2000, the total sales amount of China ASP market was 33 million dollars, accounted for 0.3% of global total sales amount. IDC is expected, the annual average rate of increase of the large China district ASP market will be 64% from 2000 to 2004, by 2004, the capacity of the large China district ASP market will reach 243 million dollars. China ASP market began to sprout when the beginning of 2000, remains the market for an unripe initial stage now, it show as the market store medium and small-scale specializing in using and serving Company that comes up to a large number in, it is mainly those traditional independent software developers , system integration trader and .com Company. But company these possess heavy competitiveness too at ability and Company scale that itself provide service.Internet of our country develops after going through fanatically, begins to tend towards reason and norm this year. It is exactly while summarizing and adjusting website's industry's development path now, we need to think and know Internet's own characteristic and advantage again for this. Its characteristics, such as high-efficient, simple and direct, individualized, resource-sharing, crossing over space-time and relatively cheap cost, etc., it is the motive power that it must use high-speed development. At the present, those companies specializing in offering service of using still face the challenge. First of all, in among being IT trade, is it is it serve these kind of mode far accept by masses even to use to sell, because most traditional trades have not realized yet that ASP way can bring the interests to them; Secondly, how to sell the application program in a kind of way which is similar to the whole solution, it is all important problems that ASP manufacturers face how to make pricing system; Finally, how be through offer application program service and traditional software sell mode participate in the competition, it is a question that China ASP should be pondered deeply too. And at present, the operation principles of most websites are remote from above-mentioned advantage and characteristic in Internet, the trains of thought of operation of websites seem that still stays in management mode and management theory in old era. But at the same time, the current situation of the Chinese market is that the competition is being aggravated constantly among enterprises, e-commerce is developed rapidly and ten millions of small and medium enterprises all generally lack the fund and well-trained job IT personnel, these reasons will promote the development in China of this kind of mode of ASP too. The scale of website of this kind of mode is like large-scale enterprises or large-scale company too, we can say although the sparrow is small, the five internal organs are available. A key job of believing that in the near future , the content will be made and the customer service will become websites. Even make the respect in the content, needn't make personnel totally regular and centralized either. The most emerging technology has already made us able to finish the organization, exchange of the webpage, format and transplanting in the twinkling of an eye on Internet directly, the huge administration inwebsite's company and personnel management organization will have passed out of existence; With the progress of the society, human life will be closely linked with Internet , website company is it invest a large amount of manpower and huge fund is it cover the sky and the earth , promote get households of propaganda of type to go on to need; And Chinese enterprise choose factor that ASP consider especially at the manufacturer concentrate on data security guarantee , professional IT quality respect of personnel too. Meanwhile, because such new service form confidence insufficient to ASP, reliance of degree one quite general phenomenon too to ASP manufacturer prestige. Rank choice factor after the factor these include the price , implement speed and expansibility of application program ,etc. also. But we are looking forward to, ASP service business that will be developed soon, will offer sectional system integration of the module service for website's construction. It can make individual set up homepage with perfect function need to set foot in any technological development even. So website operation can get rid of huge technological development and maintain organization from then on, this is the developing direction of ASP and trend of the market in the future. If we call it as making the undertaking totally all living key of websites to the future, that will not exaggerate at all. IDC thinks that in two years in the future, ASP market of China will move to maturity progressively, certainly will eliminate a batch of commercial modes in the unclear or company that one's own ability is worse too, by 2003, China ASP market will demonstrate the trend of steady growth. And in coordination with the applied software market, vertical trade ASP market, SCM applied software market, CRM applied software market will be that China's development will be very fast in the following two years, field of having more commercial opportunities.。

ASP外文翻译+原文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 backstage supporter , 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 must also 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 betweencustomer 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. On essence, 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 thethree-layer structural special case of Client/Server that applied on Web.In the system of Browser/Server, user can pass through browser to a lot 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 software only , 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 for database , update etc. function, submit operation result to Web server.Careful analysis is been easy to see , the architecture of Browser/Server ofthree-layer is the handling of general affairs of the two levels of structure ofClient/Server logic modular from the task of client computer in split , from the first floor of individual composition 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 ofBrowser/Server of three-layer. This kind of three-layer architecture following picture shows.This kind of structure not only client computer from heavy burden and the 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 computer handles 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 of program 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 of Client/Server compare with all advantages that not only have the architecture of Client/Server and also have the architecture of Clinet/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 ofBrowser/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 user of 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, browser is 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 customer end 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 large to have reduced the requirement for customer end, customer end become very " thin ".System 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, directly join with database server because of client computer, user can very easily 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 directly linked 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, is that 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 of Client/Server , are developing to the Web application of distribution type 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 or Server 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 ／S architecture 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 the structure 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 in front( 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 customerend 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 the structure 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 working station 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.The technology of main stream of management software technology is as 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 of developing pattern technical configuration. C/S is that American Borland company researches and develop most early, B/S is that American Microsoft researches anddevelop. 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 self cry 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 be called 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 customer application 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 the software 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/S is 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 and maintenance 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 operating system 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 what operating system, and in fact the most of websites do not use windows operating system 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。
