survey paper on coupling measurement tools in object oriented software

In software engineering, coupling is the manner and degree of interdependence between software modules. It is a measure of how closely connected two routines or modules are, the strength of the relationships between modules. Low coupling is a sign of a well-structured computer system and a good design. A large numbers of metrics have been projected for measuring properties of object-oriented package like size, inheritance, cohesion and coupling. As object oriented analysis and design techniques become widely used, the demand on assessing the quality of object-oriented designs substantially increases. Recently, there has been much research effort to develop and empirically validate metrics for OO design quality. The coupling measurement metrics are more useful when they are correctly measured. This paper contains the survey of types of coupling measurement tools that are available till the date.
