Active Object-Relational DataBase Management Systems (ORDBMS) react to the occurrence of predefined events automatically by the definition of Event-Condition-Action (ECA) rules. Whenever an event occurrence causes the triggering of multiple rules at the same time, the execution model of an active ORDBMS requires an explicit trigger rule conflict policy which regulates the selection and execution of multiple triggered rules. The rule execution model provide a mechanism known as rule scheduling which performs the ordering and execution semantics of multiple triggered rules to handle the trigger rule conflicts.
