Abstract

Most object databases offer little or no support for eventbased programming over and above what is provided in the programming language. Consequently, functionality offered by traditional database triggers and event-condition-action (ECA) rules has to be coded in each application. We believe that a notion of triggers should be offered by object databases to facilitate application development and a clear separation of concerns. We present a general and flexible event model that unifies concepts from programming languages and database triggers. We describe an implementation of the model and how it can support the requirements of a rich variety of applications.
