Frank,
I recommend you take a look at
www.xcase.com ... you can reverse engineer all your SQL Server, Oracle, VFP etc databases into it and when you make changes it creates a compliant script for whatever backend you choose to make necessary changes totally automatically.
"... 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
