基于XML的异构数据库集成中间件的研究

Research of heterogeneous database integration middleware based on XML

为了有效地利用信息资源,实现数据共享,提出了一个基于XML的异构数据库集成中间件的解决方案。着重阐述了该中间件的设计思路和各个模块的功能和实现过程。通过实现关系数据到XML数据的转化、集成,该中间件屏蔽了各个异构数据源的平台、系统环境、内部数据结构等方面的异构性,为用户提供了一个统一和透明的访问接口。

In order to exploit the information resources effectively and realize the data sharing,this paper proposed up a solution proposal of heterogeneous database integration middleware system based on XML.In this paper elaborated emphatically the middleware design concept and function and implementation process of each module.Through the realization of transformation and integration from relational data into XML data,this middleware shields all differences in aspects of data source including the platform,system environment and internal data structure,and so on.It provides a unified and transparent interface for users to implement the accession.
