CIMS环境下基于对象的信息集成框架

信息集成是实现ＣＩＭＳ的关键．文中在集成模型的选择和集成系统的设计上引入了面向对象的思想，提出了一个基于对象的信息集成框架，并着重讨论了本地对象模式和全局对象模式设计和实现的关键技术．与传统的信息集成方法相比，基于对象的信息集成技术能更自然地表达已有数据库之间的语义信息，并保持已有应用程序的独立性，而且具有良好的可扩充性．

AN OBJECT BASED FRAMEWORK TO INTEGRATE INFORMATION IN CIMS ENVIRONMENT

Information integration is a key issue for CIMS. By introducing object oriented ideas in integration data model and architecture design, an object based framework to integrate heterogeneous ,distributed and autonomous information in CIMS environment is proposed. The design of the local object schema and global object schema is presented in detail. Compared with traditional approaches, this approach can express more naturally the semantic knowledge existing between the data repositories, not only having little influence on the original applications, but also making the system extend easily.
