An Event Based Approach to Web Service Design and Interaction

This paper advocates an approach to web service design and interaction that is based on web services simultaneously participating in shared business events. In contrast to one-to-one method invocations, such events are broadcast in parallel to all web services that participate in it. Moreover, the transactional business events are distinguished from non-transactional attribute inspections. The paper first discusses the role of the business event concept as the cornerstone for a methodical analysis and design phase. Then, it is shown how the event broadcasting paradigm can be implemented by means of SOAP messaging.
