分布式计算机体系结构及中间件技术探讨

对分布式计算机的两层、三层和四层体系结构和特点进行了分析，对基于分布式体系结构的中间件技术，特别是事物处理中间件的特性、体系结构和应用进行了探讨．指出：中间件属于可重用构件，目前趋向于用构件技术来实现，建立模型和规范是促其发展的核心，与中间件发展相辅相成的分布式多层体系的开发也要考虑诸如开发环境、应用程序的集成与配置等技术问题。

Study on the distributed computer architecture and the middleware technology

The distributed computer's two-layer,three-layer and four-layer architecture and features are analyzed.Moreover,the middleware of architecture-based,especially the business-handled middleware's feature,architecture and application is studied.It is pointed out that middleware belongs to reused-component which realizes technology of middleware,to establish model and criterion is a core of developing middleware,the development of distributed architecture that is supplement with the development of middleware must be taken such factors into account as its environment,the integration and configuration of application-program and so on.
