Abstract : Reliability is one of the main challenge that encounter Web services compositions. Due to the inherent autonomy and heterogeneity of Web services it is difficult to predict the behavior of the overall composite service. Current related technologies are unable to resolve this problem efficiently. These technologies rely on two existing strong approaches: transactional processing and workflow systems. In one hand transactional processing ensures reliability. However, they are too rigid to support process based applications like composite Web services. On the other hand, workflow systems focus mainly on coordination and organizational aspects and ignore reliability issues. In this paper we propose a new solution that combines the business process adequacy of workflow systems and the reliability of transactional processing. We introduce the concept of transactional patterns to ensure reliable composite services. A transactional pattern can be seen as a convergence concept between workflow patterns and advanced transactional models. We show how we use it to define composite services and how we ensure their reliability according to the designers specific needs.
