Description: The design and implementation of the online examination system based on the J2EE architecture
This paper implements an on-line examination system based on J2EE platform design, integration of the XML technology, constructs the distributed system based on J2EE enterprise Web architecture, make it become a cross-platform distributed system. At the same time with the tools of Rose combined UML language and Web application development, visual modeling, using UML use case diagram, class diagram, sequence diagram and collaboration diagram, component diagram and deployment diagram, define system requirements, described the system design, the Web page, the component object, data table and database as a class or object, according to the
Modeling the view of the real world, designing and developing steps according to the viewpoint of software engineering. This system based on J2EE architecture, make full use of JSP, JavaBean, Servlet, XML components and the flexibility of three layer model to simplify the development process, optimizing the performance of the system, so as to improve the development value of the system.
