【摘要】 本文简述了网络计算的模式的演变与发展，讨论了分布式计算的最新技术，并以分布式对象技术的特点、Windows DNA分层体系结构概念以及COM+规范为技术背景，探讨了校园网环境下高校校务系统的实施方案，最后采用UML建立了基于数据库的分布式工作流系统模型并给出了系统的实现框架。这种新的分布式系统开发方式可以把应用系统看作一组关于服务的集合，服务可以由一个或多个COM+组件组成，这些组件可以物理分布在不同的地方，并且能够被所需要的应用程序复用，从而使整个应用系统具有易集成、升级、而向多用户等特点。更多还原

【Abstract】 This paper expounds the evolution and development of the network computing model, discusses the new technology about distributed computing. In this thesis, the concepts and principles of distributed object computing technology and COM+ standard are introduced with windows DNA architecture. On the foundation of that, the paper discusses the implementation method of a management system for universities based on the campus intranet. At last, it provides a distributed workflow system model based on database, the UML model is designed and combined with above technology. Through this development method, the application system is thought as the set of service that is consisted of one or more COM+ components. These COM+ components are physically distributed in different places and are reused by the needed application system. So that the application system in wide area is easily integrated, upgraded and faced by multiple users.更多还原
