In last few years, Dynamic metrics was hot area of research in software engineering. A number of studies have explored how dynamic analysis can measure the quality of Object Oriented Software. Most of the studies utilized dynamic coupling, cohesion and complexity metrics to assess the quality of software. Unfortunately, the use of such metrics has not been practically validated. They were just implemented on small programs and their use for practical applications has so far not been thoroughly investigated. To clarify this problem, this paper presents a new approach for dynamic analysis of object oriented systems.
