Question { iFlex, 27551 }

what is difference between procedure and function,
procedure and trigger?

Answer

he major difference to keep in mind is that trigger code is hard-parsed every time the trigger runs. You should therefore code all of your trigger actions in stored procedures (preferably implemented in packages, per good programming practice), and limit the trigger body to a PL/SQL block that just invokes the procedure.
