数据流图的生成编辑的研究

Generation Edit of Data Flow Diagram

本文提出并初步实现计算机辅助的数据流图(DFD)生成编辑(GE)。DFD的GE思想,是基于对DFD和数据字典(DD)的形式化描述,通过需求调查工具、DFD工具和DD工具的结合,生成编辑DFD和DD。对传统的支持结构化分析(SA)的软件工具中的DFD、DD计算机辅助编辑而言,是新的尝试。

In this paper, a computer-aided Generation Edit (GE) of Data Flow Diagram (DFD) is presented and implemented. Based on formal description of DFD and Data Dictionary (DD), the requirement investigation tool, DFD tool and DD tool integrate with each other and generate DFD and DD. For the computer-aided edit of DFD and DD in the traditional software tool supporting Structured Analysis (SA), it is a try.
