数据流图到结构图的转换工具DTST

A Software Tool for Deriving HSC From DFD

根据分层结构设计HSD 方法和原理,我们具体实现了一个数据流图DFD 到分层结构图HSC 的转换工具DTST。它是软件分析与设计支持环境DSE 中的工具之一。该工具可以帮助用户在软件开发的概要设计阶段从数据流图半自动地导出分层结构图。导出过程中,还可同时生成模块说明书和字典。此外,用户还可以对所导出的结构图进行交互式的编辑、修改、存储、管理等。

We have developed a software tool DTST which transfers DFD into HSC according to principles of Hierarchical Structure Design method (HSD).The DTST is one of the tools in soft- ware analysis and Design Support Environment (DSE).It can be used to help user derive HSC from DFD semi-automatically in general design phase of software development,and module declaration is produced simultaneously.In addition,the user can also edit,modify,store,and manage the derived HSC interactively.
