Improving the quality of software cohesion metrics through dynamic analysis

Class cohesion is an important object oriented software quality attribute. Assessing the class cohesion and improving the class quality accordingly during the object oriented design phase allows for cheaper management of the later phases. Most of the cohesion metrics planned in the journalism describes static cohesion measurement at design level. Static metrics is a measure that is applied at the design level. Dynamic metrics is some measures that are performed at object level. It provides more accurate cohesion value as compared to the static metric. Dynamic cohesion performed measurement and provide good approach into behavioral aspects of the system. Dynamic cohesion measurement provides the capacity of cohesion metric at object level and using various object oriented characteristics such that encapsulation, polymorphism, parameters for the period of measure. Dynamic cohesion metrics introduce the correct meaning of the measurement and then define measures, validation and verification. The dynamic cohesion metrics are validated by using byte code, java applications to find the affected class and performs changes into it. The execution based approach is used to measure module cohesion of legacy software. The cohesion metric is based on definition-use pairs in the dynamic slices of outputs. This approach significantly improves the accuracy of cohesion measurement. The dynamic technique is applied on the static metrics and measures module cohesion that will give more appropriate values of cohesion.
