Event-driven Reactivity: A Survey and Requirements Analysis

Despite the huge popularity of event processing nowadays, there is a big gap between the potential usefulness of event-driven pro- cessing and the current state of the practice. One of the main reasons is the lack of a comprehensive conceptual model for the event-triggered reactivity and the corresponding framework for its management. In this paper we survey the current state of the art in event-driven architec- ture with special focus on event and action processing. We describe the prerequisites of a completely novel conceptual model for describing re- activity that is more close to the way people react on events: based on the ability to identify the context during which active behavior is rele- vant and the situations in which it is required. This approach opens a completely new view on the event processing as the way for managing a very valuable knowledge asset of every enterprise - knowledge how to react (make decisions) in event-driven situations.
