“…This paper takes the radical approach to completely replace the While metrics for the traditional functional decomposition and data analysis design approach measure the design structure and data structure independently, object-oriented metrics must be able to focus on the combination of function and data as an integrated object [2]. The evaluation of the utility of a metric as a quantitative measure of system quality was based on the measurement of a system quality attribute.…”

Abstract-This research seeks to describe concepts and techniques to improve the quality of the object-oriented System. Object-oriented design is a popular concept in today's system development. Many metrics relating to product quality have proved their value for system maintenance and modification. The paper introduces the use of three traditional metrics and presents six additional metrics specifically for object-oriented systems. The object-oriented metrics criteria selescted are used to evaluate the system attributes. A brief description of the object-oriented structure is given. Each metric is then described, interpretation guidelines given, and the applicable quality attributes listed. Future work will be to define criteria for the metrics. Acceptable ranges for each metric will have to developed based on the effect of the metric on desirable system qualities.

“…If a large number of methods can be invoked in response to a message, the testing and debugging of the class becomes complicated since it requires a greater level of understanding on the part of the tester. A worst case value for possible responses will assist in the appropriate allocation of testing time [17,9,21, 1].…”

“…Classes (objects) are coupled when a message is passed between objects; when methods declared in one class use methods or attributes of another class. Inheritance is the hierarchical relationship among classes that enables programmers to reuse previously defined objects including variables and operators [17][18][19][20]22].…”

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.

“…To evaluate the quality of object-oriented programs, many metrics have been proposed, which are related to various language features like class size, coupling, cohesion, inheritance, encapsulation, and polymorphism [4][5][6][7][8][9]. In previous studies, these metrics are generally applied to fault prediction [10], class testability prediction [11], code refactoring [12], and code size estimation [13].…”

Abstract-There has been a long debate on which programming language can help write better object-oriented programs. However, to date little response is given to this issue with empirical evidence. In this paper, we perform a comparative study on C++, C#, and Java programs by using object-oriented metrics, which comprise measures for class size, complexity, coupling, cohesion, inheritance, encapsulation, polymorphism, and reusability. Our experiment is conducted on 78 tasks in Rosetta Code, a code repository providing solutions to the same programming tasks in different languages. The experimental results show that: (1) C++ classes are significantly larger than C# and Java classes in size, but their complexity does not differ significantly; (2) C# classes are significantly more likely to be coupled than C++ and Java classes through inter-class method invocations instead of direct data access; (3) C# and Java classes tend to be more cohesive than C++ classes; (4) C# and Java significantly outperform C++ in building deep inheritance trees; and (5) programs written in C++, C#, and Java do not show a significant difference in class encapsulation, polymorphism, and reusability. These findings could help practitioners choose suitable languages to develop object-oriented systems.
