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!
