>>So, it seems to me that VFP file tables are really hard to maintain. We keep on reindexing files at least 3 times a month. The system that I am currently handling is a hospital system which has volumenous records at least 4,000 invoices a day. Our client is getting angry why they need to do such thing? Is SQL Server a silver bullet solution for this?

Here, I had to rebuild the same table twice, both times for the same customer, on the same workstation, because the network cable was switched from one machine to another, and probably got loose in the process. But that is all I had here. Most of the machines have UPSes (even workstations), electricity is stable, and you don't get the house electrician to lay down the network cables (well, most of the time).

I agree. The only time my tables have been corrupt is when I did something foolish. The hospital network is stable, the users are well-trained not to turn the machine off unless tech support has tried everything else. No curruption. No maintenance on my part.
