| 摘 要： | 通过网络进行数据共享是数据库互联的根本目的.但是内、外异构现象的存在,使得数据库共享往往不能顺利实现.从数据库异构现象产生的根本原因出发,研究解决这个问题的方式与方法.提出在网络数据库管理系统前端增加＂跨库检索＂和＂重新组织＂模块,以分别解决内和外部异构带来的数据共享困难,并设计了相应的解决方案,进行了相应的实践.

| Abstract: | The ultimate purpose of database interconnection is to share the data by network.But the existence of interior and exterior isomer makes it difficult to achieve database sharing.Building on the rooted cause of isomer database,the solution to the problem is studied.Add "trans-database retrieval" and "re-organization" in the front end of network database management system are put forward to settle the difficulty in data sharing caused by the interior and exterior isomer,and a corresponding solution with corresponding practice is designed. |
