摘要
管理信息系统开发的核心技术是数据流程图的设计。数据流程图既是新系统逻辑模型的主要组成部分,又是系统物理设计的重要依据。本文根据自己在科研及教学中的经验总结出数据流程图的设计方法,供同行商讨。
The Designing of Data Flow Diagram(DFD)is the key technologyin the developmentof Management Information System(MIS).DFD is notonly the key composing part of thelogic model in new system,it is alsothe key basisin the system physical designing.Based on theexperiencesthe authors acquired in scientific re-search and teaching,The papersums up the de-signing method of DFD for discussions with col-leagues.
