Determine Cohesion and Coupling for Class Diagram through Slicing Techniques

High cohesion or module strength indicates that a system has been well partitioned into components which have strong internal relationships between attribute, method and class. Cohesion is an important factor in term of software design. Coupling indicates the degree of interdependence among the component of a software system. Coupling is thought to be a desirable goal in software construction, leading to better value of internal attribute, such as maintainability, reusability and reliability. A coupling metrics capture the degree of interaction and relationship among class dependency graph element attribute and method in software system. The Slicing technique using to slice the class dependency graph, Program slicing describes a mechanism which allows the automatic generation of a slice. In this paper, we proposed a new technique for Cohesion and Coupling for Class Diagram through Slicing Techniques. Proposed new techniques show the class dependency graph, dependency between attribute-attribute, attribute-method and method-method. Result indicate that the propose scheme significantly low coupling and high cohesion, so system are more reliable, efficient and credibility of class diagram is appropriate.
