As we know that,Logical Tables are created when we do any operations like Insert,Update and delete on Tables.
Basically,Logical Tables are used by Triggers for the following reason:-
1). To test data manipulation errors and take suitable actions based on the errors.
2). To find the difference between the state of a table before and after the data modification and take actions based on that difference.
3). To insert,update or delete records in another tables based on this tables.
