Trigger is a pl/sql block that is automatically invoked on an event, when any DML command is used on corresponding table.
Triggers are classified into different categories based on when they are to be fired and where they are to be executed.

-Row level Triggers
   -Before Insert
   -Before Delete
   -Before Update
   -After Insert
   -After Delete
   -After Update
-Statement level Triggers
   -Before Insert
   -Before Delete
   -Before Update
   -After Insert
   -After Delete
   -After Update

Depending on the requirement we can fire the trigger when ever we want the pl/sql block to be executed
