中间件技术在异构与互操作环境中的应用研究

Research and Application of Middleware Technique in Heterogeneous Database and Interoperability

为了解决现代化企业信息系统由于分布性、可扩展性和可重用性导致的信息系统的结构设计复杂的问题,实现异构数据库间数据共享和互操作,采用中间件技术,简化了信息系统的开发,通过对CIS需求的分析和对中间件介绍．描述了基于J2EE中间件技术的CIS体系结构设计方案;特别是对于非结构化数据库和结构化数据库并存的异构环境,通过设计基于．Java技术的访问中间件模型,实现了异构数据库的互操作．

In order to reduce the complexity of CIS structure design, which is caused by the distribution, expansibility and reusing of information system in modern enterprises and especially to solve the problem of data sharing and mutual operation in heterogeneous database, middleware technique has been applied to simplify the development of information system. By analysis of the needs of CIS and the introduction of middleware, a design plan which is bases on J2EE middleware technology CIS system structure is described by this paper. Especially heterogeneous conditions coexistence regarding the non-structural database and the structural database, through the design based on the Java technology of middleware model, has been implemented the heterogeneous database inter-operation.
