基于CORBA的通用数据存取中间件研究及实现

DESIGN AND IMPLEMENTATION OF UNIFY DATA ACCESS MIDDLEWARE BASED ON CORBA

数据是应用系统运行的基础 ,中间件的发展为数据存取提供了新的途径 .CORBA作为一种常用的分布式对象标准 ,其对数据存取的方法十分重要 .本文结合领域数据特点 ,提出了一个基于 CORBA的面向数据存取的中间件模型 ,完成了对数据的通用表示、常规操作等功能 。

Data is the foundation of application system, and the development of Middleware provides a new approach for data processing. As a common distributed object standard, CORBA makes it possible for constructing data access middleware. Combining with the characteristics of domain data, this paper puts forward a data access oriented middleware model, which realizes the services such as unified data representation, routine database manipulation etc, and conquers the integration problems of new systems and legacy systems in some way.
