Abstract
In this paper we investigate the definition, detection, and management of events in the active object-oriented database system SAMOS. First, we present various event specification facilities based on simple but nevertheless powerful constructs which support the modelling of time aspects as well. Second we show how events can be detected in an efficient way. Finally, we deal with the internal representation of events using the benefits of the underlying data model.
