XCFG Based Data Flow Analysis of Business Processes

A lot of service-based business processes have been developed with the rapid growth of cloud computing. Ensuring the data flow correctness of business processes is very important, which needs capturing the data flow firstly. In this article, an XCFG(eXtended Control Flow Graph) based approach is proposed for the data flow analysis of business processes defined in BPEL specification. With XCFG modeling BPEL process, the improved equations for reaching definitions are defined to take the new characters of XCFG into consideration. Then iterative algorithm is adopted to solve the equations so that the definitions that may reach each XCFG node are computed. Case study shows the effectiveness of the proposed approach.
