Without knowing it, Barking Dog Prime means that he conceives a dbms as
a formal logic system that should handle missing data in a
deterministic manner as opposed to non deterministic method incarnated
by SQL NULLS. On that, he is right 100% and you are wrong.
The only flaw in Bob's reasonning that he simply can not imagine that such formal system has a one purpose: bridge the gap between subjective and collective interpretation of data and formal structual representation of data. In the precise case of missing data, he can not conceive that a perfectly relational system should both satisfy conditions of formalism and subjectivity to be succesfull. As a consequence, he can not accept a second that even if they are fundamentally wrong on a logical level (with all consequences we know of), NULLS are supremely succesfull into representing subjectivity into a system....
So do me a favor, do not engage him, he is lost cause for inquisitive and questionning purposes... Received on Fri Oct 06 2006 - 21:55:34 CEST
