A Study of Software Metrices Coupling and Cohesion

Software quality in context to software engineering refers to two different notions which are namely Software Functional Quality and Software Structural Quality. Software functional quality could be defined as something that reflects how well a function complies with a given design where as on the other hand software structural quality refers to how well a function meets to non functional requirements. Software crisis refers to the difficulties faced in writing useful and efficient computer programs. These crises are mainly due to the rapid increase in computer power and complexity of the problems that could be tackled. With the increase in complexity of the software, many problems arise because methods are neither sufficient nor efficient enough. In this research paper we are going to present object oriented metrics coupling and cohesion. They can be use as a powerful tool in not only gaining knowledge about the quality of the software but also help us to check the complexity of the system.
