except for a HD failure and software bugs, SQL SERVER don't lose dataYes, I've used SQL Server for over a decade and have been highly inpressed with its stability.
But I've also seen data loss on flaky networks with PC freezes. If there are issues on the PC or between the PC and the server, converting to SQL Server will not fix those. A data entry clerk can carefully enter a scrreen of complex data, then the #$^$^%$$^ PC freezes again and the work is lost. You need to fix whatever is causing the freezes.
This isn't an argument against SQL Server. It is an argument for investigating the cause of the freezing, not just changing database which seemed to be the proposed solution at the start of the thread.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
