摘要
在简要介绍了分布计算相关技术后,针对企业ERP技术平台及应用模型所应具有的特点分别进行了技术上的分析.通过对CORBA、COM+、J2EE、WebService等分布式框架中的技术及应用性能进行较为系统的研究和比较,结合企业的需求,采用CORBA作为企业ERP的技术平台.CORBA具有跨平台、跨网络、跨语言、跨协议、跨版本、开发商中立等诸多特性,它的极强的适应性比较适合企业当前及长远发展的需要.对于应用模型,设计了一种基于CORBA的C/S和B/S混合模型,此模型中的B/S部分,采用四层浏览器 Servlet CORBA EIS结构,对整个模型进行了详尽的论述和分析.最后给出了一个应用这种模型的正在企业良好运行的ERP的一个功能模块———供暖收费系统.
The technologies related to the distributed computing are reviewed,and the characterizes of enterprise ERP technical platforms and application models are analyzed. Combining with the enterprise demand, the application performances and technologies of CORBA with those of COM+, J2EE, Web Service, etc are compared. The CORBA as ERP platform are adopted and CORBA is specified for a system that provides interoperability between objects in distributed environment, including different platforms, networks, languages, protocols, versions and independent providers. CORBA's strong adaptability meets the current and future demand. For application purpose, a B/S-C/S mixed model based on CORBA is designed and described in detail. The B/S part adopted the four-layer browser-Servlet-CORBA-EIS architecture.A ERP function module for heating charge management system is presented,which has been working well.
