Abstract. The active database theory is well
developed; many different types of events are
supported, static analysis mechanisms are developed,
etc. One of the problems regarding active rules
management is a number of rules defined; it is not so
easy (for a user and for a system) to manage a large
number of rules. Although some systems allow similar
rules grouping, the problem is still significant. During
a project we had the same problem occurred i.e. a
number of time triggers that were used was too big.
This paper describes how we reduced a number of
time triggers that were used in a multiagent system by
introducing a meta-trigger.

Keywords. Trigger management, active databases,
reactive agents
