Functional requirements of every participant are analyzed, and use case analysis model is established. On the basis of use case analysis of every participant, functional features of this system are summarized, and the system is divided into several independent modules. Database models are designed for every functional module. Database modules include conceptual model and table structure model. According to database table structure model, database creation SQL statement is created. Database tables are acquired on the basis of SQL statement. The technical of J2EE is selected as system development technical, Struts and JDBC are selected as system development technical combination. Struts is responsible for logic process, JBBC provide API for database access. The system is divided into several layers of View, Action and DAL model. Functional classes and methods are designed for every function, and the system is accomplished and interfaces are designed.Online examination system in the campus network running steady and provides technical support for the examination work.
