1、 密级： NANCHANG UNIVERSITY 外文翻译 THESIS OF BACHELOR （ 2012 2013 年） 题 目 基于 ASP 的 Web 应用程序开发 学 院： 计算机 系 软件学院 专 业： 计算机软件 班 级： 093 班 学 号： 8000609130 学生姓名： 李世明 指导教师： 朱 玮 Develop Web application program using ASP the architecture that must first establish Web application. Now in application frequently with t
2、o 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 pa
3、ttern 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 ste
4、p, 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
5、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 support
6、s 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 use
7、r. 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 compute
8、r 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
9、 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 between customer and server is not immutable. Some In
10、ternet 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 cust
11、omer, 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 structure Along with the development
12、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
13、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:
