A review of Coupling and Cohesion metrics in Object Oriented Environment

Software metrics are used to check and evaluate various aspects of the complexity of a software product. Coupling and Cohesion are considered to be the most important attributes. The increasing need for software quality measurements has led to extensive research into software metrics and the development of software metric tools. Many Software Metrics have been proposed for object oriented paradigms to measure various attributes like complexity, cohesion, software quality, and productivity. As object oriented analysis and design appears to be at the forefront of software engineering technologies, many different object-oriented coupling and cohesion metrics have been developed. To maintain high quality software, developers' choice is always low coupled and highly cohesive design. The aim of the paper is to reinforce the existing coupling and cohesion metrics specifically used in object oriented environment, to analyze their significance in software development, expose their limitations and some suggestions for further investigations.
