CIMS信息集成平台中的数据模型

为了满足ＣＩＭＳ环境中信息集成的需求。本文为信息集成平台设计了一种具有集成功能的面向对象的数据模型ＩＣＯＭ．ＩＣＯＭ数据模型不仅具有行为的封装与重载，继承与继承、行为的提炼与迟后联编和多态性等面向对象的特征，而且还能够很好解决集成过程中出现的各类冲突，即模式冲突与数据冲突。

DATA MODEL FOR A CIMS INFORMATION INTEGRATION PLATFORM

To meet the needs of integrating information on CIMS environment,this paper designs an object-oriented data model ICOM with integration functionsfor the information integration platform. The ICOM data model not only has object-oriented features, including encapsulation and overriding of behaviors, inheritance and multiple inheritance, refinement of behaviors, late binding, and polymorphism, but also can well resolve conflicts during schema integration, such asschema conflicts and data conflicts.
