Rajesh:

If performance is a concern, then you need to consider how much bandwith you have. VFP works well on a good LAN, but will be painfully slow over a WAN because it's a file server database. To process a query, it has have to drag a lot of information over the netowrk to the client.

If your on a WAN, then you need something that will process queries in the server's memory space and return only the result set. You can either purchase SQL Server or you can accomplish the same thing by using a VFP COM object on server to process query and return an XML result set.
