Examples

Post by steve » Fri Apr 30, 2010 5:16 pm

I am (very) new to Rel and relational databases. I need to understand them in order to use them experimentally
to model various situations and events.
I have read Hugh Darwen's Intro to Relational D'base Theory and Chris Date's magnum opus 'Intro to D'Base Systems',
and am full of admiration for the principled development of D.
But I am still having problems getting my syntax accepted by Rel whenever I stray off into trying more complex queries and operations. The above books are systematic but have not systematically developed my competence in the language of D

I've read the grammars and tried to apply them but somehow, what I really need is a set of incrementally more complex examples where actual commands are displayed.

Is there a source that covers actual commands of increasing length and complexity?

kind regards
steve

The latest edition of Darwen & Date's "The Third Manifesto" (http://www.amazon.co.uk/Databases-Types ... 0321399420) is probably the best reference, but unfortunately there isn't a general Tutorial D or Rel manual that provides incrementally more complex examples. Yet.
