Considerations of Service Assembly Based on the Analysis of Data Flows between Services

Service composition research mostly focuses on the dynamic (workflow) aspects of compositions. In this paper we consider the static component of service composition and focus on analyzing the data flows between services within a composition. We argue that compatibility of service interfaces is a necessary precondition for service composability, and we show that data flow analysis can be applied to the problem of service composition design to identify compatible service interfaces and to minimize data coupling between services.
