摘要
针对分布式数据同步时因为有异构的数据源而造成数据格式不统一,应用层进行同步的时候要进行相当复杂的转换并且维护起来也要耗费相当大的成本,提出了利用XML来统一异构数据源的格式,构建基于XML中间件的虚拟数据库。介绍此系统下的异构数据集成的思想和实现框架,同时详细介绍了该框架提供的服务功能及实现的关键技术。
An efficient method is proposed to convert heterogeneous data to consistent format and maintain it's cost on applicaition tier when we synchronize distributed data. Aimed at the issue, to unify heterogeneous data sources by use XML and build the XML - based virtual database. We presents our idea and implementation architecture of heterogeneous data integration are presented udem this system. Meanwhile, the service functions and the key methods of the architecture are described in details.
