Abstract

A database system includes a trigger gateway for implementing trigger functionality. The trigger gateway is located at a communication point between a user and a database system. The trigger gateway receives database commands destined for the database and processes triggers associated with the database commands. Where appropriate, the trigger gateway forwards the database command to the database. A trigger action server, which is located remote from the trigger gateway, may execute trigger actions in response to trigger execution requests sent from the trigger gateway. Alternatively, trigger actions may be executed within the trigger gateway. Trigger processing includes the processing of triggers after failed database commands. Security features are implemented to prevent unauthorized database access through the use of triggers.
