Conceptual Modeling of Events as Information Objects and Change Agents

Traditionally, semantic data models have not supported the modeling of behavior. We present an event modeling approach that can be used to extend semantic data models like the entity-relationship model and the functional data model. We model an event as a two-sided phenomenon that is seen as a totality of an information object and a change agent. When an event is modeled as an information object it is comparable to an entity that exists only at a specific point in time. It has attributes and can be used for querying and specification of constraints. When an event is modeled as a change agent it is comparable to an executable transaction schema. Finally, we briefly compare our approach to object-oriented approaches based on encapsulated objects.
