Triggers are procedures that are stored in the database and
are implicitly run, or fired, when something happens.
Traditionally, triggers supported the execution of a PL/SQL
block when an INSERT, UPDATE, or DELETE occurred on a table
or view.
Triggers support system and other data events on DATABASE
and SCHEMA.
