CSC W系统中间件的设计和实现

Design and Realization of the CSCW System Middleware

随着CSCW应用程序在许多领域的广泛使用,越来越迫切地需要开发一种支持协同工作的通用平台,由它来提供该类系统中必要的协作功能和通讯服务,以避免在开发不同应用程序时对这些功能的重复设计.文中在分析协同应用需求的基础上提出了CSCW系统中间件设计思想,建立了中间件模型及其基本控制机制.通过使用面向对象方法实现中间件的程序设计,并提供了一套完整的API,便于用户在此基础上进行各类协同应用程序的开发.

As CSCW is used widely in many fields,there is an increasing need for designing a platform, which can provide the necessary cooperation services and communication services in CSCW system to avoid developing the basic module repeatedly.Based on the integrated analysis of CSCW application requirement,this paper introduces a middleware design model and its basic running mechanism.In addition, object oriented design method is used in building middleware system.A set of class libraried and APIs is provided on which developers can build new CSCW application system in component based mode with higher efficiency and code reused rate.
