Effectiveness of Software Metrics for Object-oriented System

Software metrics has been utilized to evaluate inheritance as well as to assist the designer in order to focus on product quality as well as cost estimation in all the lifecycle stage of development of the final product. To pertain measurement through the diverse level of class hierarchy, a person can evaluate inheritance with reuse, to acquire the best computation of abstraction levels of a object oriented system. In our paper, a new metric of hierarchical inheritance is proposed that measures the quality of the program through different levels of Object-Orientedness, and we named it PLHIM: Per Level of Hierarchical Inheritance Metric. The main idea behind proposed metrics and research work was to make use of measurement as a criterion for improvement in software development at different levels to minimize risk and this has been done by taking the problems of C++ and Java.

Design plays a key role in the development of software. The quality of design is crucial and is a fundamental decision element in assessing the software product. The early availability of design quality evaluation provides a better way to decide the quality of the final product. This avoids presumption in the quality evaluation process. Hence Software Metrics provide a valuable and objective insight of enhancing each of the software quality characteristics. This paper proposes a quality model to assess the design phase of any object-oriented system based on the works of Chidamber, Kemrer and Basili and suggests two new metrics. The research focuses on analyzing a set of metrics, which has direct influence on the quality of the software and creating a metrics tool based on Java that can be used to validate the object-oriented projects against these metrics. The analysis is carried out on a set of real world projects designed using Unified Modeling Language, which are used as test cases. These metrics and models are proposed to add more quality information in refining any object-oriented system during the early stages of design itself.
