by the oracle engine when an DML action is performed.
Trigger consists of three parts
A trigger statement
A trigger restriction
and the triggering action
Functions are different from procedures as
functions return value whereas procedure doesnt
To carry out set of tasks a certain pl/sql statements are
grouped in a procedure.
After performing some tasks and returns the result(function)
functions are written explicitly by the user.
