Database system event triggers
A technique for database management includes receiving an indication of a selected scope of a trigger. The scope is selected from a plurality of scopes of database management. The scope can be on the level of an individual table, or a schema associated with a user, or the database itself, or a system of databases, among others. The technique also includes receiving an indication of a selected event that belongs to the set of one or more events associated with the selected scope. Trigger metadata is stored that identifies both the selected scope and the selected event. A technique is also described for executing a process in this database management system. Flags indicative of one or more applicable events of the selectable events are loaded into a private cache of the process and checked when a new event occurs.
