政务网络信息系统的异构分布式数据库研究

Research on heterogeneous distributed database in government network system

在当前政务网络信息系统中,多个部门系统数据库之间存在明显的异构性,独立性和自主性,使不同部门之间的信息交流成为难题。采用局部数据集成技术在网络信息中心构建互连通讯平台,开发部门子系统进行数据查询、接收、核对、确认等方法,能够实现政务网络信息系统异构分布式数据库之间的信息共享。

It's difficult to take the information exchange in the current government network systems, because the heterogeneity and independency among the databases of many departments are evident. The information share is realized in heterogeneous database, such as making up interlinked platform based on local data integration technology, developing subsystem in order to realize data query, acceptance, checkup and affirmance etc.
