Application Development Of J2EE-based ERP-SRM System

Enterprise Resource Plan, which came into China at the end of last century, is a kind of advanced management thought. Being developed about fifty years, ERP becomes a necessary tool in modern enterprise. It is an import flag of the degree of enterprise's modernization and information management.With the development of computer science, the architecture of ERP system evolves from the early host system to the later client/server model and then to the multi-lays distributed architecture. It makes the system to get better expansibility. Using Web technology, people can find that browser has been the actual client of three-lay model or multi-lays model in the more and more popular web architecture.J2EE is an architecture which can simplify the development, deployment, management and other relative complicate problems of enterprise solution projects. And J2EE architecture can provide middleware integrated frame to meet the need of low cost, high ability, high reliability and high expansibility.According to the project of TongFang ERP-SRM system, the thesis dose the following study on development of ERP-SRM system based on J2EE.1. Discussing the principle and function model of ERP and J2EE technology, the advantage of ERP system based on B/S over that based on C/S.2. We have yielded ERP-SRM system software based on J2EE.By fully analyzing the demand of the enterprise, this software realize ERP-SRM system based on B/S using J2EE architecture. Now the development task has finished, the software is under test.3. Designs the whole system from two ways: The traditional modular analysis method and multi-lays architecture. So the whole system can be considered a multi-lay component one, which has a few relativities whatever in its breadth or its depth. Furthermore, the system has flexibility, availability, expansibility and testability.4. Analysis the issues such as interface and security of the system.
