Research & Development Of Enterprise Information Management System Based On J2EE

With the quickly development of science and network technology, people realize more and more importance of information to our society, and the enterprises understand more importance to constructing information system. Now many middle and small enterprises have constructed their MIS based on simple software architecture of Client/Server model. There are some limitations such as low degree of opening, low compatibility. J2EE technology and it's component based model simplifies enterprise development and deployment. As one of new standards of distributed object, the J2EE platform manages the infrastructure, crosses platform and supports the Web services to enable development of secure, robust and interoperable applications. Applying J2EE technology to enterprise information management system will make up for the shortage of traditional information management system.The Model-View-Controller pattern discards disadvantages which the design pattern in traditional web application has. It separates the control of the data and the view of the data so as to meet the demand to the multi-layer web application complicated more and more. Because I adopted the pattern of MVC based on J2EE in the enterprise information management system, I simplified the work of each stage , normalized the development of whole system,increased the code quality and the system efficiencies, made the system have many advantages, such as able to cross platform, easy to be extended and maintained etc. The system manifests the technical advantages of J2EE architecture and MVC pattern.Information management Technology has developed from the Electronic Data Processing to Supply Chain Management. At present there are many skilled ERP software. They are all powerful but costliness, and more suit to manufacture enterprise but middle and small enterprise. It is expensive and wasteful to middle and small enterprise, especially to business enterprise. Besides, some manufacture and management module is unavialbe to themselves. It's a problem who can starve to solve that how can supply middle and small enterprise with information system economically and efficiently. In this article, the author sets up a new system on thebasis of J2EE technology.After discussing the theory and the support techniques of the management information system, the dissertation introduces the detailed development process, such as requirement analysis, database design, application design, function design and realization of the system, and so on.
