Difference between database triggers and form triggers?

A database trigger is fired when a DML operation is fired on some database table. On the other hand form triggers are fired when user makes some event like pressing a key or navigating between fields of a form. A database trigger can be fired from any session executing the triggering DML statements. While form trigger is specific to the form. Database triggers can cause other database triggers to fire. On the other hand, form triggers cannot cause other form triggers to fire.
