WWW文档协同写作系统中通信中间件的设计与实现

THE DESIGN AND IMPLEMENTATION OF THE COMMUNICATION MIDDLEWARE IN WWW DOCUMENTS AUTHORING SYSTEM

ＷＷＷＤＯＣ是一个基于ＴＣＰ／ＩＰ协议的分布式协同写作系统．ＤＯＣＯＭ作为通信中间件将客户和服务器有机地联系起来．本文分析了ＤＯＣＯＭ的设计任务和目标，介绍了ＤＯＣＯＭ的对象模型、通信接口和公用服务．实践证明，ＤＯＣＯＭ既简化了客户／服务器应用的开发，又提高了应用对平台的独立性．

WWWDOC is a distributed coorperated authoring system based on TCP/IP. DOCOM, a communication middleware, brings the client and server together. In this paper we analyze the design task and aim of DOCOM and then introduce the object model, communication interface and common services of DOCOM. It has proved that DOCOM not only simplifies the development of C/S applications, but also improves the independency of applications from platforms.
