An optimization rule for activexml workflows

Abstract

Web services are used as the de facto standard to develop the modern business applications that require collaboration and coordination among the business partners. ActiveXML (AXML) is viewed as a data-oriented workflow language for specifying the Web service calls and their interactions. The present workflow engines execute the workflow specifications strictly without attempting to optimize the Web service calls. This paper proposes an optimization approach as a rule called , to improve the performance of workflows in the context of AXML. The groups the Web service calls of AXML documents, and reuses the existing results of other equivalent Web service calls. © 2009 Springer Berlin Heidelberg.
