Research And Development Of An Integrated Management System Of Modern Distance Education

The paper gives a detailed introduction to the design and development of the comprehensive management information system of modern remote education of H.N.U. The system can provide students, teachers, school managers and local managers with management service corresponding to respective management roles and perform various kinds of management by linking to some sub-systems. The main purpose of this system is to provide many assistant management services such as teaching management, archive management, performance management, test management, fee management and BBS management for school managers. The system employs the three-tier Brower/Server model, and uses JSP as the middle-ware. Users can run this system with a browser.The platform is Microsoft Windows 2000 Advanced Server and the Servers include Tomcat5.0 as the Web server and MS SQL Server2000 as the Database server. Developed with JSP technology, a dynamic Web technology, the system is able to form homepage dynamically using the server scripts and perform many functions readily when used with the JavaBeans components. Java Database Connectivity (JDBC), a new technology that uses JDBC-ODBC bridge drivers to communicate with varies data source, is used to access background database. In the process of access date from database, this system runs by three ways which include direct access, importing bean and creating database connection pool. The system uses multi-page showing technology in some models needed to display numerous data by many pages. This system's developmental technology is mainly characterized by its making use of a series of technologies based on J2EE and the MVC model applied masterly to the Web application programs. The main creative point is that the common MVC model is improved , a mixed MVC model based on double Servlets is designed and implemented, and the new model' s performance by using this kind of structure is analyzed.The paper introduces the system from the following aspects: the design target, the technology project of development, the structure model, the design and implement, the key technologies, the security and optimization of performance. The paper focus on the function, the structure and the performance of this system.
