| 摘 要： | 1.引言网络的发展使不同数据库系统之间的互操作在物理层成为可能,但要真正实现,还得依赖于逻辑层的处理,即数据库系统之间的交互。由于不同数据库系统之间的异质性和封闭性,使得这二技术实施起来很困难。

| Abstract: | In the heterogenous mulit-databases environment, the interoperability of different database systems is becoming more and more important. Now there are four main ways to handle it, such as gateway, mulit-database system, distributed database system, federated database system. In this paper,we compare and analyze them by networking method,and we think federated database system is a better choice. In addition,we introduce the design structure of the federated database system-LNFDBS being developed by us. |
