Codd in 1970, huh? I bet he was the life of the party back then. 'Hey baby, wanna come back to my place and discuss set theory?'

Option D is the clear winner here. Relational databases are about as hierarchical as a pancake. Flat is where it's at!

Hmm, I'm going to go with option D as the incorrect statement. Hierarchies are for those who can't handle the flat world of relations.

Option D is definitely the incorrect statement here. The relational data model is not a hierarchy, it's a flat structure with tables and relations between them.
