>>Goes to my point that saying ADO .NET is not a data/database engine is an EIF (Excercise in Futility).
Au contraire; insisting that "Age of Empires" is a data engine and demanding proof from people who prefer to think it is a game, could be considered to fit the definition of at least one psychiatric diagnosis.
"... 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
