Analysis of quality of object oriented systems using object oriented metrics

Measurement is fundamental to any engineering discipline. There is considerable evidence that object-oriented design metrics can be used to make quality management decisions. This leads to substantial cost savings in allocation of resources for testing or estimation of maintenance effort for a project. C++ has always been the most preferred language of choice for many object oriented systems and many object oriented metrics have been proposed for it. This paper focuses on an empirical evaluation of object oriented metrics in C++. Two projects have been considered as inputs for the study — the first project is a Library management system for a college and the second is a graphical editor which can be used to describe and create a scene. The metric values have been calculated using a semi automated tool. The resulting values have been analyzed to provide significant insight about the object oriented characteristics of the projects.
