Online Examination System Based On J2ee Architecture Analysis And Design

The research and realization of the examination system on Network based on J2EE model, belongs to the field of computer network and communication. In this thesis, the examination system, whose background is "the examination system on network", a reform project in education of Linyi medical college, is mainly described.This examination system combines the advanced teaching management procedure and modern network technology, and makes use of many advanced technologies such as Jsp, servlet, Javabean. The functions include the exam pool managing, the manually/automatically produce in paper, the examinee's information managements, the examination control, the announcements and the inquiry of results of examination. In the thesis, many problems such as the links among web pages, the security of web page's transfer, the database interface, the limiting of test time, separating show layer from business logic layer, how to realize the separation of the business with javabean, the organization of connections to datahase with jdbc, how to realize the MVC model in this system and the design of database backstage are solved.In the server, the system platform adopts windows2000, which shows good security, operation stability, easy management. Database is SQL server2000. SQL server is easy to use,whose elasticity and integrated degree to combine with other relevant software is wonderful.The design on storey of user's view uses J2ee technology which has good portability , high efficiency when compiling code , convenience of the connection with database.This text specifies the livelong process, including requirement analyse, system design, design in detail, and other key technologies the system involved.
