分层数据流图的自动生成与布局

Automatic Generation and Layout of Hierarchical Data Flow Diagram

摘要: 本文讨论分层数据流图ＨＤＦＤ（ＨｉｅｒａｒｃｈｉｃａｌＤａｔａＦｌｏｗＤｉａｇｒａｍｓ）的自动生成、布局及其ＯＯＰ（Ｏｂｊｅｃｔ－ＯｒｉｅｎｔｅｄＰｒｏｇｒａｍｍｉｎｇ）实现技术。文中提出了规范化数据流图的概念及基于最佳布局路径和最小进层规则的布局算法。

Abstract: An automatic generation and layout algorithm for HDFD based on a SPSA database and the optimization layout path as well as layout level rule are discussed in this paper. The algorithm is performed by Object-Oriented Programming（OOP）technique using Borland C+ +2. 0.
