Manish,
If the problem is speed, a flat file isn't going to help you that much
more. You'll still have to encode and decode the data, no matter which
format you use. And even if it's faster now, all you're doing is
delaying the inevitable. You definitely need a database.
If it were me, I'd go back to them and explain why they need a database.
But I'm only a consultant...
