METHOD AND SYSTEM FOR IMPROVING QUALITY OF OBJECT- ORIENTED PROGRAM

摘要

PROBLEM TO BE SOLVED: To efficiently detect a problem point from a large scale object-oriented program and to easily pursue the cause of the problem point. SOLUTION: A measuring means 1 extracts quality information such as the size of each class, the number of times of referring to other classes, and the depth of succession from an inputted object-oriented program. A judgement means 2 compares the quality information with a previously set reference value and extracts an element (module or class) having high probability of including a problem. A reference relation analysis means 4 analyzes the reference relation of the extracted element and a rule checking means 5 detects the violation of rules. The analyzed reference relation is displayed as a picture indicating the reference relation. A timewise variation analysis means 6 analyzes the timewise variation of the quality information for the element extracted by the means 2 and displays the timewise variation as a time series variation graph.
