Codd's paper was prescient and foreshadowed many developments in the relational model. How did the operators
he define compare to the relational algebra operators of today (especially see his definition of "join")?
"Connection Trap" is interesting concept, and somewhat subtle. Cood had beginnings of the idea of "normal forms"
(he only defines 1NF though); but weak redundancy was one notion that did not lead anywhere.
