I was taught about relational database theory without any mention of 'Clinton' or 'information principle'. Shit happens. I don't smoke, either. My definition is of "is-a" is crystal clear, unlike the information principle, but I do think I invoked just that principle as an argument to justify the definition.

A reference to 'Clinton' would be most appreciated. (Google isn't particularly helpful, as expected.)
