k_murli_krishna, can you pl take a look at the attached ERD. You don't see any notation/feet in it, do you? I made this from visio. Is it OK design for OLAP model?

*Just by looking at an ERD, will you be able to tell if it is a OLTP or OLAP db?
*Is Visio a simple or advanced tool compared to ERWIN?
