SQL Server pretty much addresses any stability/capacity/programmability issues that dogged DBFs and DBCs from the beginning.

The server itself has some overhead on whatever machine it is installed, but the performance is outstanding.

It is a considerable shift from the DBF/local table operation, but once you get over the hump, you don't look back.

It also makes it a lot easier to switch front ends if desired.

>>>Forget about that approach, you are only creating problems for yourself. Either you follow some of the tips I gave you, or you use for instance MSSQL server as data storage. I do the latter, it's much more stable, it's faster with many users and it's expandable. I now only use DBFs for some lookup tables which I include in the exe, for everything else I use SQL server and cursors.
