Active databases are a combination of traditional static databases and active rules, meant to be automated mechanisms to maintain integrity and facilitate in providing database functionalities. Active database systems can react to the occurrence of some predefined events automatically. In many applications, active rules or triggers may interact in complex and sometimes unpredictable ways, thus possibly yielding infinite rule executions by triggering each other indefinitely causing non-termination. The termination of active rules is an unpredictable problem, except when rule languages with very limited number of rules are used.
