An active database is a database in which some operations are automatically executed when specified events happen and particular conditions are met. Several systems supporting active rules in an object-oriented data model have been proposed. However, several issues related to the integration of triggers with object-oriented modeling concepts have not been satisfactorily addressed. In this paper, we discuss issues related to trigger inheritance and refinement in the context of the Chimera active object-oriented data model. In particular, we introduce a semantics for an active object language that takes into account trigger inheritance and supports trigger overriding. Moreover, we state conditions on trigger overriding ensuring that trigger semantics is preserved in subclasses.
