I capiche! However it seems the most enduring contributions to any field exhibit hallmarks of elegance and simplicity (perhaps only to the trained eye) such that even previous non-adherents accept and it becomes conventional wisdom.

As my school physics teacher oft used to regale us with his "war" stories, it calls to mind the one where he was 3 years into his Phd when Bohr's Theory of the Atom was zapped. Clearly the arguments put were so compelling that he discarded years of conventional belief and started anew (or at least his Prof/Supervisor was convinced).

Whilst perhaps remaining a fence sitter (as NULLs give me little trouble in the practical sphere), I am yet to detect arguments even remotely as compelling as Codd's original exposition on the RM.

Sad but true - in IT more so than the real professions.

There is even a deeper subtext in your use of the band-aid metaphor. In fact the patient often needs a superior surgical team and ICU, yet ppl apply the band-aids hoping the aortal haemorrhage will just stop - somehow!

No - but it doesn't relieve the burden on a theorist of having to carry the day with them too. Hence my earlier comments about elegant and compelling proposals. Simple hand-waving about SQL as damaged goods or the OP championing MV systems etc doesn't seem to meet these criteria else he would be using terms like QED without challenge.
