A Comparison between Incremental Composition and BPEL

This paper describes the Incremental Composition approach and the BPEL method of composing Web services to one Web service composition. The use case and the different Web services are explained. Each approach is applied to the use case and the same service chain is developed for both approaches. The paper compares approaches, explores differences in implementation and execution, and outlines the conceptual differences between the approaches.
