Googling for 'Codd 12 Rules' finds lots of stuff - and you quickly get
close to what was in the original articles. The 'last version' might be
Codd's RM/V2 book - I don't know of anything later. Whether that would
be better than the original is open to debate. I do have a list of
URL's stashed in my browser's bookmarks if you really need them; they
were Googled several years ago, so they'd need revalidating.
