UML class diagram metrics tool

Many of the object-oriented (OO) metrics that have been proposed over the last decade can be applied to measure internal quality attributes of class diagrams. This paper describes a tool that automates the computation of the important metrics that are applicable to the UML class diagrams. The tool collects information by parsing the XMI format of the class diagram to produce a meta-data for the class diagram, and then uses these data to calculate the metrics. The paper also describes some areas where OO design metrics can be applied to improve software quality. Finally, the paper presents a case study to show the usefulness of OO design metrics in improving the quality of software.
