EMPIRICAL VALIDATION OF COUPLING METRICS FOR OBJECT-ORIENTED SYSTEM

摘要

The Object oriented design metrics can be used to make quality management decisions. The objective of this study is the examination of the connection among object-oriented design metrics. We made a survey and analyzed various object oriented metrics available in literature. We have proposed three new object oriented metrics viz. Attribute Interface Coupling, Method Interface Coupling (MIC) and Design Complexity to measure coupling. The new metrics shall help in measuring complexity of design at early stage based on coupling, designing object-oriented code as well as improve its quality by removing the anomalies and redundancy from code. These metrics have been validated by using six java based projects of different application areas. The empirical validation proves the significance of the proposed metrics.
