改进Jackson图的表达方法

Improvement of Jacksom Diagram Representation

对 Jackson图的描述方法进行改进 ,把顺序结构、循环结构的单一逻辑形式都分别区分成水平和纵向两种结构 ,改进后 ,使得 Jackson图对数据文件的描述在逻辑上更加严密 ,外观结构上也更加紧凑 。

This paper introduces how to improve representation of Jackson diagrams by converting the unitary logic of sequential structures and loop structures into horizontal and vertical structures,respectively,for more compactness and user friendliness.
