The invention relates to a software maintenance supporting device which analyzes and displays the structure of software, and its object is to divide software into clusters including plural variables and illustrate the result of the division. A software maintenance supporting device according to the invention includes variable dependence relation analysis means for extracting variable dependence relation data from a source code, and variable cluster analysis means for dividing software into clusters including plural variables, using a variable dependence relation. Also, an inter-variable dependence relation is illustrated as a directed graph in which a variable is expressed as a node and a dependence relation is expressed as a link, and variables belonging to the same cluster are highlighted. |
