基于CORBA的多级客户机/服务器体系结构及其在工程中的应用

THE APPLICATION OF CORBA-BASED MULTI-CLIENT/SERVER ARCHITECTURE IN ENGINEERING

CIMS是结合最新计算机技术、网络通讯技术、企业管理技术的综合系统工程技术 ,其目的将设计、制造、管理各领域中建立的计算机系统集成起来 ,形成相互协作的有机整体 .在实施 CIMS工程时 ,企业内部和企业外部计算机系统普遍存在机型、操作系统、编程语言等异构环境问题 ,因而选择良好的集成平台和构建合理的系统体系结构 ,实现各部门异构环境的集成就成为实施 CIMS工程的难点和重点 ,本文针对某公司 CIMS系统中关键问题 ,综合应用 CORBA技术、客户机 /服务器技术、事务处理技术、ODBC技术 ,构建 CBMCSA(CORBA BBased Multi Client/Server Architecture)的多级客户机 /服务器体系结构 。

CIMS,incorporating the newest computer techniques,network communication technique and enterprise administration technique,can integrate isolated computer systems that were built in the past in different departments into a cooperative whole.The heterogeneity of environment caused by incoordination of different departments often makes it difficult to implement a CIMS project.Thus,the establishment of a rational system architecture has become the key problem and the major difficulty if a CIMS project is to be undertaken.In this paper,a CORBA based multi client/server architecture is presented which integrates CORBA technique,client/server technique,transaction process technique and ODBC technique into a whole system.In this way,a solid foundation will be provided for integrating separate computer systems of enterprises working in a heterogreneous environment.
