Re: Table Design

Deepa ,
there are various considerations here , if your are using oracle and using proper indexes and proper query 5,00,000 records is not a big thing. I dont think you will see much difference . If your queries does full scan then may be your theory is rite
second consideration would be how the application request data . Is it randomaly from transaction type ?
Somehow I have a feeling that one table can do the job . Less maintainance and less parsing ( since u r using same table )
