Rakesh,

Latest VFP can FORCE data to be written to disk rather than being kept in a machine's OS disk cache where it is obviously susceptable to PC freeze etc.

I can tell you for sure that since VFP6, data on My notebook has rarely been corrupted or lost, even when processing millions of records in one giant hit. Obviously a notebook battery is a defacto UPS ;-)

I have seen trouble in sites with flaky networks, or badly segmented ones so that vast slews of data traverse miles of cable looking for a target two feet away, or PCs running numerous apps with a pink dragon screensaver, fifteen Word instances, an obsolete app running in DOS mode, eight browser instances etc etc... if that's what you're facing, you need to expect crashes and possible data loss, even with the data on the same PC.

The beauty of C/S and the reason why it is "an easy answer" for those whose resources can cover it is that it does protect data from some of these glitches. An unsupervised data entry clerk with the pink dragon screensaver may still see the same PC freezes, but she'll only lose the current entry and won't screw up everybody else as well. It can be an easy win if a room full of data entry clerks has been getting locked out by corruption every day without realizing that Julie's @#@#$$# screensaver is the cause of it all ;-)
