Design And Implementation Of An Educational Administration System Based On J2EE

The rapid development of education and information technology accelerates the construction of digital campus and promotes the reform of teaching method, teaching process and teaching management. Considering the need of the new era, this thesis in view of the reality and current situation of educational administration system at Taizhou University, analyzes and discusses the main technology problem and solutions in the process of system development, designs the system structure model and implements educational administration prototype system based on the implementation of J2EE. Given evaluation and analysis, the system is proved to be convenient, stable and secure, and its functionality car meet the practical need, concretely the thesis includes the following five parts:1. The new structure of teaching is proposed based on J2EE frameworkThree-leveled system structure which integrates B/S structure with practical business is used.2. The process of the system design and realization is introducedThe system analysis, the system design and the system realization are elaborated; the system need is analyzed, the design of the system structure, database and main function module of system is completed; the system function is performed with the application of techniques as components.3. Technique relating to data access is thoroushly discussed Data access technique is selected from the perspective of improving the performance of the system, and its speed is raised by using the techniques including the view, the connected pool, entity bean packaged by session bean.4. The security architecture of the system is proposedImplementation security is achieved by applying the techniques as authentication, access control based on roles, encrypt the data transmission between application server and the brower with SSL protocol.5. The evaluation data and functionality analysis of Taizhou University's educational administration system is discussed and prospects for perfection of the system is given.
