Service-oriented environments facilitate dynamic processes whose properties can be altered during runtime. The transactional support of such processes holds specific requirements that are not completely covered by existing specifications. In this paper, we introduce a life cycle model for transactional dynamic processes and analyze existing specifications(More)

This constraint impedes support of complex processes where participants may only possess limited local views on(More)

In order to be more flexibly applicable, our SQXML integration system(More)
