Cohesion Metric and its Relation with Coupling: A Class Level Variable Assessment Approach

Abstract

Cohesion Metrics is an important technical development which helps for the better Assessment Of class cohesion that is the measurement of relatedness among members In a class. The higher this relatedness is the best the performance will be. Hence this is an important feature of Object oriented systems. Present paper presents an advanced metrics. The pervious metrics have got few limitations. Whereas this advanced metrics considers few more characteristics of class Cohesion. This is based on common object parameters. Moreover this metric is statistically advanced and measures cohesion by observing the relationship between cohesion Metric and Coupling. This is cohesion measurement tool for Java and it is tested on several systems. These systems which are used for the experiment are deferent in size and domain. This test proved that this extended metrics captures other pairs of relatedness among members in a class and also the correlation between cohesion Metric and coupling.
