模型库管理系统的设计和实现

Design and Implementation of a Model Base Management System

模型库管理系统是决策支持系统的核心，其基本功能包括模型的定义、组合、存储和调用．该文介绍一个支持客户／服务器模式的模型库管理系统的设计和实现，在这个系统中，模型被视为程序模块，通过运用面向对象的方法进行组织以及对模型的远程和动态的透明调用提供支持，使实现的系统具有良好的动态可扩充性．同时，通过提供模型定义语言和模型库管理，便于决策支持系统客户软件的开发．

The MBMS(model base management system) is the kernel of a DSS(decision support system). The authors introduce the design and implementation of a client/server model base management system that runs on a heterogeneous distributed environment in this paper. In this system, a model is viewed as a program module and defined by a model IDL(interface definition language). By being organized with object oriented method and supporting remote and dynamic function (model) invocation transparently, the DSS may be developed easily and have very good static and dynamic extensibility. Also since many semantic information have been stored in the model base, the authors may develop more tools based on it to support the DSS development process.
