一个CSCW系统的设计与实现

随着计算机网络技术的发展，计算机支持的协同工作（CSCW）系统正逐渐成为人们研究的热点，协同式计算机辅助设计系统是一类典型的CSCW系统。本文在介绍了CSCW的基本概念之后，从系统组成的角度出发，提出了一个典型的CSCW系统是由应用子系统、信息共享平台、协同工作平台、协作管理平台、以及网络传输平台这五大部分组成的，并对其各部分的内容进行了形式化的描述和系统的分析，最后以我们开发的协同式计算机辅助设计系统－－CoopCAD为例，介绍了如何按照该结构实现一个具有实时性的协同式计算机辅助设计系统。

DESIGN AND IMPLEMENTATION OF A CSCW SYSTEM

With the development of the computer network technology, thecomputer supported cooperative work (CSCW) system is becoming a popular research field. The system of Cooperative Computer Aided Design (CoopCAD) is a typical application system of CSCW. After introducing the basic concepts of CSCW, from the point of view of the system architecture, this paper presents a basic architecture of CSCW system which consists of five parts: the application subsystem, the information sharing platform, the cooperative work platform, the Collaborate platform, and the network transfer platform. Then this paper formally describes and systematically analyzes the function of each part. Finally, with an example of CoopCAD′ s application, discusses how to completely implement a real-time Cooperative Computer Aided Design system according to this architecture.
