CIMS企业中的多数据库集成技术

计算机集成制造系统是一个极其复杂的系统，同时参与集成的企业之间的信息系统，包括顾各种分散、自治、异构的多数据库系统，因此，如何有效地集成这些异构信息，就成为目前实现CIMS企业的一个关键问题。我们在开发的CIM集成平台HIT－ⅡS系统的基础上，设计了扩充信息服务器类的方案，着重讨论了其中在CIMS集成平台环境下的多数据库系统的集成模式结构，及其基于Client/Server的系统结构，并提出了多数据库集成器的概念与功能结构。

The Integrating Techniques of Multi-Database in CIMS Enterprise

CIMS (Computer Integrated Manufacturing System) is a very complicated system, and there are a variety of distributed, autonomic, heterogeneous databases in integrated enterprises, hence it plays an important role in CIMS enterprise to integrate these heterogeneous information effectively. Based on the prototyped CIMS integrating platform named HIT-IIS which was developed in Harbin Institute of Technology, we design a scheme to extend the function of information server in HIT-IIS. This paper introduces the schema structure and Client/Server-based system architecture of Multi-database for CIM Integrated Platform, the concept and function structure of MDBI (Multi-database Integrator) are also proposed.
