【摘要】 随着信息技术的高速发展以及网络技术的日趋成熟，以信息技术为主导，综合信息技术和网络技术的管理信息系统正在成为现代化管理办公系统的首选。而中间件技术是在信息技术和网络技术的高速发展下一个新兴的技术，它是伴随着企业的全球化的趋势而产生的，随着企业全球化的发展，企业级的应用不再满足于单机系统和简单的客户机/服务器系统，而是向着三层和多层体系结构的分布式环境不断进步，为了解决在分布式环境下存在的问题，产生了中间件技术标准。 本文系统的介绍了中间件技术的产生、分类、中间技术标准以及组件技术EJB，对组件技术EJB做了较为详细的描述，包括EJB的体系结构、EJB的优点、EJB和三层体系结构等内容，最后论述了天津市地方科技奖励管理系统整个开发过程，包括需求分析、系统设计和实现，该系统的整个开发过程是以基于组件EJB的中间件技术和三层结构为基础，完全实现网络化操作，项目申报和评审过程都通过广域网进行的，打破了传统的C/S两层结构的局限性。本文的研究成果对于提高地方科技奖励评审过程具有现实意义，同时也对其他信息系统的开发具有借鉴意义。更多还原

【Abstract】 With the development of IT and the maturating of network, the management information system, which is lead by IT and integrated with network technology, becomes the preferred modern official system. The middleware is a new technology under the development of IT and network, it is booming while enterprises trend to be global. The enterprise’ application is no longer satisfied with stand-alone and simple Clint/Server system, but developing towards 3 layers and multilayer distributed environment. In order to solve the problems under distributed environment, the standard of middleware technology came into being. This article introduced the start, classification, and standard of middleware technology, described the groupware technology EJB in detail, including the architecture, advantages of EJB, EJB and 3 layers architecture etc. The article also dissertated the develop process of Tianjin local science and technology award management system, including demand analysis, system design and implement. The development of this system is based on EJB and 3 layers middleware architecture, completely realized network operation, both the application and evaluation are carried through WAN, breached the limitation of traditional 2 layers C/S structure. The research achievement of this article is helpful to the local science and technology award evaluation process; at the same time it could be used for reference for development of other information systems.更多还原
