Or a failure to understand that atomic symbols (ie ^, *, &, 0, 1, 2, a, b, c,...) are infact atomic. And also a failure to apply normalization (process of replacing duplicates with ref to original) until it is no longer possible.

Having joined the thread near its 200th posting, your understanding is slightly off context. I do not claim a db consisting of 2-col tableS is impractical [insert Mark Twain].

I claimed that, for some applications, in order to avoid NULLs, one would have to resort to generic modelling, which in the extreme case results in a db with just one 2-col table, and is impractical. If one implements www.xdb1.com/Example/Ex076.asp they should see that pattern emerging. After 223 postings, still no one has. Will you be the first? Received on Thu Mar 04 2004 - 22:08:40 CET
