Hi, Jagadeesh
I would suggest you 2 solutions:
1. to use a function to edit these fields. That way you will be sure
that you will not forget to update both tables.
2. use a trigger on master table. If I understand you - the history
table could be filled using trigger, when data in master table changes.
That way you could change only master table in your application.
Good luck!
