利用CORBA技术构造异构数据库管理中间件

Heterogeneous Database Management Middleware Based on CORBA

论述了中间件在异构数据库访问中的应用与不足,同时提出了利用当今流行的分布式对象计算技术CORBA构造数据库访问中间件的方案。该中间件对不同的数据源提供了统一的程序接口及调用界面,同时提供数据安全代理及负载平衡等管理,为实现异构数据库的透明访问开辟了新的途径。

<Abstrcat>The shortcomings of the middleware and its applictionin in heterogeneous database access are proposed.In this paper CORBA application database access is discussed,and CORBA based middleware for database management is proposed.This middleware provides the same interface for the different data sources.At the same time,data security proxy and load balance are provided.And makes transparent accessing heterogeneous database become possible.
