辅助软件开发工具DTOOL的设计及其应用

本文提出了一种面向屏幕的辅助软件工具ＤＴＯＯＬ的总体结构，主要功能、实现方法、生成机制、开放效益及在ＤＴＯＯＬ环境下开发ＭＩＳ时有关应用系统概念模式的建立步骤，本文重点讨论在ＤＦＤ及功能分解后如何进一步的建立ＩＤＳ及ＴＤＳ并最终地产生一棵面向屏幕设计的结构构树，这种开发思路将有助于一切其它面向屏幕的软件工具环境下对ＭＩＳ开发的概念模式的描述，这将大大提高软件开发效率，改善开发和维护性能。

The Design and Application of the Software Development Aid Tool DTOOL

his paper discusses the structures, functions,realization, effects of the software development aid tool(DTOOL), which serves as a oriented interface design environment, the conceptual models for development MIS include creating DFD, function divide, IDS and TDS,it is very important, how to develop IDS and TDS, finaly to creat the logic struction tree. They are can support MIS development, in any general oriented interface aid tool, it can make development and maitenance easier and improve the efficiency of MIS development.
