Daniel,

Thanks for responding. The tests are for individual patients, but I was wondering if you could elaborate just a little on the safety features of an SQL Server vs VFP database. I've done some study, but what specifically is done in one and not in another for safety's sake. Is there self-monitoring for corruption in SQL Server? And what would it do about it? Report or fix?

Thanks again,
