New Quality Metrics for Object-Oriented Programs

Some software metrics can be used to measure the program quality. Coupling metrics, as one type of quality metrics, are used in impact analysis and other maintenance tasks. In this work, we proposed new coupling metrics that measure the method calling relationships between classes. We also conducted experiments on five open- source systems to evaluate the effectiveness of the new measurement. The case study demonstrated that our proposed software metrics can complement the use of existing quality metrics to measure the software systems.
