Student's Internet Curriculum System Based On J2EE

This subject clarifies mainly component technology and model design, then offers an available frame in the use of inter network application program, that is, Model-View-Control (MVC),and take the online course selection system for example to realize it. MVC model separate the business login and the interface show in theory and its propulsion bring great significance in the development and application of Web. Form the frame structure to component design, ruse and the advantage of J2EE frame structure itself, as well as the model design make the system more easy maintenance extension and reduce difficulty in reusing the code and design. Base on Curriculum and student performance management system is a very key role, system to the students and Investigation Course, and facilitates the management of teaching and student achievement in the time of admission, What is more important is to facilitate the school's academic management.The system uses SqlServer as a background database servers use Apache Tomcat 5.0. Eclipse+Myeclipse and use integrated development environment for editing JSP, Java document.The technology highlights : Based on the three-tier structure of the MVC model, using the popular Struts and Hibernate portfolio for the design, Struts to be spent on major pages of logic control, a form of treatment, System Logic lasting Hibernate is used as middleware, and the use of DAO design model. DAO mode is the core business methods and specific data sources to increase between layer, thus reducing the coupling of the two. Just a simple right through the use of DAO pattern on the part of the core business does not have to involve how to operate the database. Thereby greatly enhancing its portability. Design use the DAO mode is the core J2EE design patterns kind. It is mainly used to handle business logic. Hibernate and run through business logic, database query, insert, delete, update operations. HIBERNATE to Hibernate as a very lightweight object encapsulation, making can spend more time processing layer in the design. Because Java is cross-platform, the system could result in a variety of operating systems, and has good security, fault-tolerant and expansive.The system has realized the student information management, for information management, and other functions logged results. Users who use IE browser visit the relevant site, the importation of the correct user name and password after the successful landing, Users can conduct operations. Administrators example of the use of it is also very convenient and efficient, scientific and reasonable for the staff, curriculum, class management. The system of the client hardware standard is not high, just above the 5.0 browser, Accessing the Internet can be. But right server hardware configuration requirements relatively high, but on the hardware market at present circumstances, This configuration has a more universal.
