## What are Triggers?
Triggers are MySQL programs that are executed automatically in response to an event. They are associated with tables. More specifically, a trigger is invoked in response to events that change the contents of a table like the __INSERT__, __UPDATE__, and __DELETE__ statements. Triggers can be invoked before or after these events take place.
