As the importance of software measurement increases, there are more researches developing the new software measure. Given the importance of object-oriented development techniques, one specific area where this has occurred is coupling measurement in object-oriented systems. This thesis presents the coupling measure COM based on the methods and OOC based on the classes in measuring the coupling of object-oriented systems. And, it evaluates them using the coupling properties suggested by Briand while it compares them with other coupling measures by applying them to a system developed in the language of C++programming language.
