Design And Implementation Of Graduation Project System Based On J2EE

With the expansion of the enrolment of the university graduation in China, The people which graduated from college is increasing.The amount of work is big and the efficiency is low for the guidance mode in a traditional graduation designis.In view of this situation, the goal of this paper is to guiding the teacher and students and provide a convenient communication platform between the group members.The system used J2EE and tools of Eclipse+MyEclipse,SERVER2000SQL database, apply MVC design patterns, and adopted Javascript and AJAX technology.The system mainly included some function modules.for example:notice public announcement, short message, folder, mission, online exchanges and contacts, discussion question-answering etc This paper includes four parts:system analysis, database design, system overall design, system function realization.In this paper, the sysytem is based on B/S(Browse/Server) model.It mainly discussed the dom4j,which is a recursively traversing algorithm, data paging algorithm based on access frequency, and using the time complexity for testing.The analysis results show that it can effectively, faster and more accurate to make the teacher and student exchange of information, improve the working efficiency, reduce the burden of the teachers and the students, and provide a very good teaching platform for teachers and students.
