I read that Codd was supposed to publish a new book on the relational model this Fall, but I can't find anything in Books in Print or Forthcoming Books in Print. Does anybody know what the status is? Also, I've seen a very short description of Codd's 12 rules, but there are a couple which I'm not quite clear on. The article references Computer World, but gives no issue data. Can anybody give me an issue #, or another book title which gives a thorough (and accurate) description? Also, Is Codd on the net?

Can anybody give me an issue #, The Computerworld article in which Codd presented his 12 rules is titled "Is your DBMS really relational?" and was published in two parts. The first appeared in a supplement to the October 14, 1985 issue, pages ID/1-ID/9 and the second appeared in the October 21, 1985 issue, pages 49-60. Dave Beyerl ihnet!beyer

Somebody should send this to Dick Pick of Pick Systems. He
insists up and down that Pick is relational, and he dismisses
as "academic types" those who disagree.

There is an excellent article in the recent (NOV?) issue of Database Programming & Design which deals with Codd's 12 rules. Very clear & readable, and even includes some of Codd's thoughts on what the rules DO NOT say. I recommend both the article and the magazine. -=- Bob Donaldson ...!cs.utexas.edu!natinst!radian!bobd Radian Corporation ...!sun!texsun!radian!bobd PO Box 201088 Austin, TX 78720 (512) 454-4797 Views expressed are my own, not necessarily those of my employer.

The article references > Computer World, but gives no issue data. Can anybody give me an issue #, or another book title which gives a thorough (and accurate) description? The two articles appeared in the October 14 and 21, 1985, issues of Computerworld. You will also find a complete description of them in my book, Relational Database Management for Microcomputers: Design and Implementation (Holt, Rinehart & Winston, 1988).
