I beg your pardon, but it's not up to her to prove this, mathematically. If her assertion that Codd et al never made such a claim holds up to the study of the published work, then her claim of the absence of demonstrated methematical necessity for 1NF stands.

If the were to make a further claim that 1NF is mathematically unnecessary, it would be necessary for her to back up that claim. But her claim, AFAIK is not that. It is that there is no claim or proof that 1NF is mathematically necessary.

Do you see the difference?

Agreed.

I honestly never had a great deal of difficulty putting data in 1NF. On the contrary, I've had a great deal of difficulty dealing with fundamentally unnormalized data that has been put into tabular form, and masquerades as 1NF data. example: crosstabulated data that uses values as column headers.

But her expereince is that 1NF was a huge obstacle to productivity among Oracle teams, when compared to COBOL/CICS teams or Pick teams. She's got other questions as well: whether a DBMS is part of the solution or part of the problem. Received on Thu Nov 04 2004 - 14:48:44 CET
