Design And Implementation Of Distance Education Management Systembased On Web

The distance education management system was constructed in early age,the access control and information system security problem increasingly prominent,and has the function of the system already can’t meet the demand of the current vigorous development of distance education.The research team was investigated the actual need of modern distance education management,and combined with the practical application of remote education system.The architecture of this system and related functional modules is defined,the system has seven function modules: log in the platform,the student status management,examination management,teaching management,teaching resources management,recruitment management,system management.In this paper,the security of the system and the development of virtual experiment course are emphasized.The system uses the dynamic password authentication technology as the authentication system,and the development of virtual experiment course is carried out based on VRML.The system is developed based on B/S architecture,J2 EE development platform,and JAVA and SQL Server 2005 database,according to the work to carry out distance education management.We descript the system business requirements,functional requirements,non-functional requirements with the business flow chart,the system use case diagram.The team was designed the functions with the model function chart in the detailed design,design the table structure of database and the concept model at the same time with E-R graph.The function implementation of the main function interface and core code is introduced in the system implementation phase.The system can satisfy the actual need of remote education business management effectively,insurance the data security with the data delivery efficiently,and improve quality of engineering courses with virtual laboratory technology,it provides the better service for teachers and students.
