Sensoria Bibliography Site Model-driven development of adaptable service-oriented business processes
Carlo Montangero, Stephan Reiff-Marganiec, Laura Semini
abstract:
Businesses typically structure their activities with work ows, which are often implemented in a rather static fashion in their IT systems. Nowadays, system requirements change rapidly as businesses try to maintain their competitive edge, calling for similar agility of the IT systems. To this end, we present StPowla, an approach that marries service oriented architecture, policies and work ows to support the agile execution of business work ows. In StPowla, the business is modelled by work ows, whose tasks are eventually carried out by services. Adapatation is obtained by allowing the stakeholders to de ne policies that establish the quality levels required of the services. The prototype StPowla support architecture comprizes the transformation of the work ow model into executable WSBPEL to be deployed in the ODEBPEL execution engine, the generation of default policies from the model, and the enactment of the policies by the Appel policy server. The SENSORIA Finance Case Study is used throughout the paper.
