Who here pretends that an algebraic structure embodies actual 'entities?' Can you cite examples? And by the way, I suggest you read Codd's book. Pages 89-90 describe the Update operator and the justification for it. Also, you might want to look at the article "Extending the Database Relational Model to Capture More Meaning" in TODS 4-4. On page 400, where he is describing the original Relational Model, he writes,

    All insertions into, updates of, and deletions from base relations are constrained

    by the following two rules....

I could cite other instances, but I think these sufficiently show that you're interpretation of Codd's use of the word 'update' is faulty.

Didn't you know that keeping the unwashed masses ignorant is one of the primary objectives of liberal elitists? Why then are you lamenting the fact that the campaign is succeeding? Received on Fri May 23 2008 - 04:58:17 CEST
