“Way back in 1968, Childs wrote a paper outlining how set theory, relations, and tuples could be applied to data management.
And that’s where I did a double-take, because 1968 < 1970. Sure enough, Footnote #1 in Codd’s seminal paper is to Childs’ 1968 work. Indeed, Childs’ paper is the only predecessor Codd acknowledges as having significant portions of his idea.”
It seems that there was life before
God Codd after all.
