1、东华理工大学毕业设计（外文翻译） 英文原文外文翻译（一）论文题目：网上选课系统姓名：学号：班级：年级：专业：软件工程学院：软件学院指导教师：完成时间：2014年 5 月13日英文原文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 A
2、SP 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.1. The working principle of ASP When the
3、Web site into the ASP feature, will take place the following things: （1）the user browser address bar to enter a URL, the default page of the expansion are. Asp. （2）the browser request to the server. （3）the server engine running ASP procedures. （4）ASP document in accordance with the order from top to
4、 bottom starting with the implementation of the script orders, the implementation of HTML page content. （5）pages of information sent to the browser. 2. ASP operating environment Asp need to run in under the PWS or IIS. PWS or IIS services in windows98 or windows2000 on the fringe of the CD-ROM, can
5、use the Add / Remove Programs in the Add / Remove windows components to install. Asp and the general need to access databases or a combination of SQL Server database, made a powerful process. ASP can run the web server software Windows2000 default installation is IIS5.0 (internet information server)
6、, and the default installation of windows xp is IIS5.1, windows 2003 default installation of IIS6.0. PWS (personal web server) running windows98 environment in a simple personal Web server. 3. ASP and the meaning of ASP (Application Service Provider, application software rental service providers) re
7、fers through the Internet to provide application software rental services industry, refers to the application software industry as the mainstay, and through one-to-many network Transmission services, such service-based business transactions to be leased by the way, in a more cost-effective manner ha
8、s the right to use the software, and also because the industry centralized management and greatly reduce the cost of maintaining enterprises .1Basically, ASP is a software services, Internet services, and outsourcing of information services and network integration and access of products, access prod
9、ucts, such as the three major characteristics, can even be seen as ISP ( Internet Service Provider) and ITS (Information Technology Service) combination. ASP is the English Application Service Provider, the standard Chinese translation is application service provider, is defined as commercial or ind
10、ividual customer management applications to provide solutions for companies or enterprises. ASP Chaozuo recently by the media is very fiery, the IT industry is not facing a pile of technical terms it is very difficult to clarify terminology ASP content, the paper tried to use simple language to the
11、broad masses of readers opened the mysterious veil of ASP, IT Top of the ASP industry areas have some basic knowledge. 4. Origin of ASP The research to ASP mode and ASP enterprises origin can proceed with two respects , one to in terms of business and technology , is it carry on research to come fro
12、m ASP developing history that business commit; Another one is studies the origins of ASP enterprises and evolution course at present in terms of organizations development.Whether stand up synthetically above-mentioned developing stage, to put it briefly, present ASP history and development path of p
13、rovider can simple to describe as:The first, developed from the past ISP, rounded the infrastructure and communication function, cooperate with software manufacturer, increase the business scope, develop into the present IDC (the data centre of Internet)；The second，the past ISV (independent software
14、 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 encapsulat
15、ion 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
16、 , 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 capaci
17、ty of system integration trader.5. 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
18、extent, ASP field relevantoutstanding behaviors at the capital market of Company just cause peoples 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
19、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 HTML plait writ
20、es 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
21、 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 procedur
22、e. 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 pa
23、ge. 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 inspectiona
24、l 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 A
25、SP 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 the personnel i
26、f 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 connect
27、s. 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
28、 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 expens
29、es 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 appl
30、ies the complexity problem of the procedure. 6. 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 o
31、rder 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 scrip
32、t 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 co
33、mputerized 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 SQL language is currently in transition from the relational form (the ANSI SQL 92 standard) to a newer obje
34、ct-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 co
35、mmonly implemented; our touchstone in defining basic SQL is to provide a syntax that is fully available on most of the major RDBMS products.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 ou
36、r 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, noth
37、ing 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
38、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
39、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
40、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
41、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 in order to represent a product of a table with itself. The differen
42、ce 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 f
43、orm, 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 appli
44、cation, 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
45、 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 enviro
46、nment 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.7. Visual Basic Database Access prospects With the recent Web applicati
47、on 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 s
48、trategy 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 easy solution possible.东华理工大学毕业设计（外文翻译） 汉语翻译汉语翻译Active Server Pages（ASP）是服务器端脚本编写环境，使用它可
