一种设计和实现结构图结构编辑工具的新方法

A new designing and implementing method for the diagramatical design tool of design structure diagram

设计结构图是一种功能强大的图形描述语言 ,它不仅有丰富的数据结构和控制结构 ,而且在并发处理、实时处理、大型软件开发等方面均提供了相应的支撑设施 .本文重点讨论设计结构图的设计原理、系统结构。

Design Structure Diagram(DSD) is a diagrammatic design tool applied in large-scale,real-time and concurrent software designing. It is more structurized,more expressive,and deeply reflects some fundamental principles of software engineering than other diagrammatic tools. DSD editor is a syntax-directed editor which is based on DSD. This editor can be widely applied in many fields, such as software design,program understanding,software maintenance,complexity measurement,etc. We introduce DSD and its editor,then focus on the discussion of its design principles,system structure, work procedure and its implementing method.
