Papazoglou, Michael P. (2003) Web Services and Business Transactions. UNSPECIFIED.
Process oriented workflow systems and e-business applications require transactional support in order to orchestrate loosely coupled services into cohesive units of work and guarantee consistent and reliable execution. In this paper we introduce a multi-level transaction model that provides the necessary independence for the participating resource managers, e.g., local database and workflow servers, of organisations engaging in business transactions that are composed of interacting web services. We also present a taxonomy of e-business transaction features such as unconventional atomicity criteria, the need for support for business conversations and the need for distinguishing between three basic business transaction phases. In addition, we review current research and standard activities and outline the main ingredients of a business transaction framework necessary for building flexible e-business applications.
