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.
