Executive Summary

Web Services Composition (WSC)-based applications are widely used in the heterogeneous environment, which has inevitably led to the need for reliable mechanisms for the WSC paradigm that can provide sustainable execution semantic. This paper focuses on constructing data flow and control flow for the composition Web services execution. A flexible compensation semantic of control flow and data flow for the long running process is proposed, which can implement composition compensation dynamically and abstract hierarchy modeling of complicated multi-partners business process.
