摘要
数据流分析（DFA）是软件开发过程中的一项有意义的工作。其成果为软件的数据流图（DFD）。对于早期开发的软件系统，将其由DOS环境升级到Windows环境，一方面是设计友好的用户界面，这可借助于Windows环境下集成化软件开发工具完成；另一方面是实现信息传递、数据处理功能，可基于软件的数据流图从DOS源代码继承过来。文章以TurboC2．0和VisualC＋＋5．0为例，对这一思路进行了初步研究。
Data Flow Analysis (DFA) is an important work in software developing work and the achievement is a Data Flow Diagram (DFD) of the software. For the early developed software system,there are two items of work should be down if they are upgraded from DOS to Windows:the first one is designing a friendly user interface,which will be implemented by integrated software developing tools under Windows environment;the second one is implementing the functions of information transferring and data processing,which will be based on the data flow diagram (DFD) of software from DOS source code. The paper gives a primary study on this subject and Turbo C2. 0 and Visal C++5. 0 are included as examples.
