An Analysis of Web Services Workflow Patterns in Collaxa
Web services have a substantial impact on today’s distributed software systems, especially on the way they are designed and composed. Specialization of different services is leading to a multitude of applications ultimately providing complex solutions. The interaction and modeling aspects of Web services is increasingly becoming important. Based on the needs for Web services conversations, process modeling, and composition, a variety of languages and technologies for Web services composition have evolved. This case study is focused on a systematic evaluation of the support for workflow patterns and their BPEL (Business Process Execution Language for Web Services) implementation in Collaxa, a leading BPEL process modeling and enactment engine for Web services processes.
