What principles are you talking about then?
If I misunderstood the principles you refer to I apologize. Codd's relational rules and designs for relational databases developed from relational algebra theory, which was introduced by... Edgar F. Codd.

If you meant to refer to some other principles can you name them or give a link or something?
You're misquoting; is that intentional? The post you're replying to says the principles that inspired/predate Codd don't require tables/tuples. Thus, the details of Codd's relational model are irrelevant.
