DYNAMIC COUPLING METRICS FOR SERVICE –ORIENTED SOFTWARE

Tóm tắt

Service-oriented Architecture has become popular and presented many advantages to develop and maintain software system. The coupling is the most important attribute of services when they are integrated into a system. In this paper, we propose a suite of metrics to evaluate service’s quality according to its ability of coupling. We use the coupling metrics to measure the maintainability, reliability, testability, and reusability of services. Our proposed metrics are operated in run-time which bring more exact results. Proposed dynamic coupling metrics are Coupling Between Services Metric (CBS), Instability Metric for Service Metric (IMS), Degree of Coupling between 2 services metric (DC2S), Degree of Coupling within a given set of services metric (DCSS). The comparison of proposed metrics and other published by TaiXu, Kai Qian, Xi He also presented.
