What is MS SQL Server Triggers?

A trigger is a special type of event driven stored procedure. It gets initiated when Insert, Delete or Update
event occurs. It can be used to maintain referential integrity. A trigger can call stored procedure.
Executed automatically when an INSERT, UPDATE or DELETE operation takes place on a table.
You can specify which trigger fires first or fires last using sp_settriggerorder.
Triggers can't be invoked on demand.
They get triggered only when an associated action (INSERT, UPDATE, DELETE) happens.
Triggers are generally used to implement business rules, auditing.

Triggers can also be used to extend the referential integrity checks
