Research and Application on Representation Tools of Software Detailed Design

When detailed design stage, need decide realized arithmetic of each module, and accurately express these algorithms. Aims at characteristics of software detailed design have too much presentation, hard to select and master. This paper researches on primary representation tools. On the base of research sequence type, select type, first judge type loop, after judge type loop and many situations select type etc 5 type control structures of structural program designing, through the method of combine pictorial representation with textual description, emphasize research representation of these 5 type control structures use representation tools, the representation tools of research contain flow chart, box diagram, problem analysis diagram, and IPO diagram etc 7 types. The research contents of this paper are reference and guide of software detailed design, and it has important guiding significance for software designer.
