you donīt understand me. ;) I know this 12 rules and i know the 9 rules from codd also. But now i search the original white paper, written by codd, with his 9 rules. And i think he had not only wrote down his 9 rules, maybe he had additionaly wrote some elucidations and his thoughts. Iīd like to download his original paper , witten by him.
