## Triggers

A trigger is a special database procedure (a sequence of statements) that the database system executes after a specific event occurs.

You can define the following types of triggers:

● Triggers that are executed after an SQL statement changes data in a base table (or a view table based on this base table).

● System triggers, that the database system executes after the database instance is restarted.

You can define as many triggers as required.
