基于CORBA和XML的中间件设计与实现

Design and Implementation of Middleware based on CORBA and XML

目前,中间件(Middleware)在解决异构平台的通信问题上应用越来越为广泛,但由于其功能繁琐,使用复杂,价格昂贵,很难适用于小型企业异构数据集成通信。针对此问题,提出了一种中间件框架实现――基于CORBA和xml的中间件。该中间件通过xml定义统一的访问请求格式,运用corba原理和JDBC来进行对远程异构数据库的访问操作.框架设计实现了该中间件可移植,性价比高,可扩展性,易操作性的特点,适合于小型企业应用。

Now, middleware technology have applied in solving the communication problem of different platforms ever-broad. But it is difficult to fit for the integration communication of different platforms in small corporations because of its miscellaneous functions, complex uses and dear price. In this paper, we propose a middleware frame-the middleware based on corba and xml. The frame uses xml to define the uniform require format , applies the corba theory and jdbc technology to carry out the operation on long-distance database. The design of frame realizes the characters as transplantability, extensibility, high ratio of price and function, easyoperating, which is fit for small corporations.
