Complexity Metrics for Service-Oriented Systems

Service-oriented architecture is emerging as one of the primary research areas in software engineering and one of the key technologies to the integration of enterprise information system, development of distributed software system. Complexity is an important aspect for software quality assessment and must be appropriately addressed in service-oriented architecture. In this paper we introduce the features of service-oriented systems for the analysis of a system´s complexity. We analyze the key aspects in measuring service-oriented systems. On the basis of complexity metrics of product metrics for service-oriented infrastructures, we improve the complexity metrics by considering factors that influence the complexity of service oriented systems. Finally, we propose a set of complexity metrics for service-oriented systems.
