| Abstract | Active database management systems (ADBMSs) support the specification of reactive behavior in the form of event-condition-action rules. The capability to modify the definition of reactive behavior is a crucial part of the ADBMS-functionality. Rulebase evolution is however a complex problem in systems that support composite events, particularly when event occurrences should be taken into account that have occurred prior to the modification. We describe which kinds of rulebase modifications are meaningful and should thus be supported by an ADBMS. We investigate syntactic and semantic aspects of rulebase evolution, and present an algorithm for rulebase evolution for the object-oriented ADBMS SAMOS. |
