【摘要】 为充分利用数据库的资源,研究了在分布式异构数据库中实现数据分布与交换的"主存"中间件实现方法。利用XML跨平台特性和主存,辅存的工作原理,结合基于服务的中间件技术,运用于分布式异构数据库系统中。系统以访问"主存"中间件服务器中最新XML数据为主,访问相应子系统为辅,通过复制分段方式实现数据的一致性。该方法在一定程度上提高了数据处理效率,实现了数据传输同步机制。更多还原

【Abstract】 For the full use of database resources,this article studies the method of the"main memory"realization of the data distribution and the exchange in the distributional isomerism database.The method uses the cross platform characteristic of XML and its working principle of the main memory/additional memory,and combines service-based mid-ware technologies.The system,by visiting the"main memory"in the server,the newest XML data primarily and visiting corresponding subsystem as an auxiliary,realizes data uniformity through duplication partition.This method enhances the data processing efficiency to a certain degree.It realizes a mechanism for synchronical data transmission.更多还原
