【摘要】 ERP(Enterprise Resource Plan,企业资源管理)是上个世纪传入我国的国外先进管理思想,经历近半个世纪的发展,目前已经成为现代企业管理中不可或缺的有力工具,是企业现代化和信息化程度的重要标志。随着计算机技术的发展,ERP系统山早期的主机系统进化到后来的客户/服务器(C/S)模式,然后又向灵活的多级分布式结构转变,企业管理软件系统的体系结构跨入三层式/多层式体系结构,增强了系统的扩展性。随着Web技术的发展,越来越多的ERP系统开始转向基于Web的架构,浏览器成为三层/多层结构事实上的客户端。J2EE利用Java技术来简化企业解决方案的开发、部署和管理。J2EE体系结构提供中间层框架用来满足高可用性、高可靠性以及可扩展性的应用的需求。论文以清华同方ERP-SRM系统开发课题为背景,对基于J2EE的ERP-SRM系统做了如下的研究:1.讨论了ERP管理思想和功能模块以及J2EE相关技术,B/S结构的ERP系统与C/S结构的ERP系统相比的优势。2.研究并参与开发了基于J2EE的ERP-SRM系统软件,这套软件在充分深入企业调研用户需求的基础上,采用J2EE体系结构,实现了B/S模式下的ERP-SRM系统。目前软件已经完成了开发任务,现处在上线测试阶段。3.使用二种不同的概念方式来研究应用系统:传统的模块分解方式和多层体系结构。这样使整个系统成为一个多层的组件系统,以实现系统横向、纵向之间的弱耦合,使系统具备了灵活性、可重用性、可测性、可扩展性。4.对ERP-SRM系统的接口和安全性等问题进行了分析。更多还原

【Abstract】 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.更多还原
