Various approaches have been taken towards modelling and definition of event processing systems, the dominant ones being: using rules, using SQL extensions, and using scripts. Yet, there are some semantic structures that are expressed by all of them, providing the opportunity to raise the level of abstraction and create semantic model of event processing. This talk will describe the major different types of event processing from the point of view of the role it plays in computing, describe some common design patterns, and then describe the idea of the semantic approach to event processing, the semantic abstractions that are required in order to achieve it, and its possible automatic mappings to various implementations. The concepts will be demonstrated by a comprehensive example.
