Primitive event


An atomic event is considered to be indivisible and instantaneous.

Key Points

If an event is non-instantaneous, then it is possible to divide into a beginning of this event (an initiator) and an ending of this event (a terminator). Therefore, atomic events must be instantaneous. In active database literature, the concept primitive event is typically used instead of atomic event. The major reason is probably that system primitives and application primitives are not distinguished.
