The Design And Achievement Of Teaching Management System Based On Component Technology

As one of the development standards and architectures of distributed software, CORBA technology is increasingly developed and imporoved. So it's of great practical significance and commercial value to research on CORBA technology. The first purpose of the paper is to study and research on basic theory and architecture of CORBA and basic knowledge and implementation mechanism of middleware. Then I mainly research on the design and development of multi-tier distributed applications based on CORBA. Also combined on the design and developoment of Web test system of experiment center of computer institute, I deeply understand and study the main technology and implementation method of using Jbuilder and Visibroker for Java to develop distributed applications based on CORBA. At the same time I compare some mainstream technology of distributed technology. In the procedure of designing and developing system I use the development method of multi-tier structure on considering it's comprehensive and distribution. Some interfaces like test or exercises have been defined, then were distributed to middle logical service layer. In order to convenient using of system for teachers and students, friendly client server interfaces based on CORBA aimed at exercises and test have been established. Also some other functions like information issuance, information and Internet communciation have been established. So it's of great space for component reuse and retractility of system.
