No, there are more difficult subjects that he avoids, such as schema evolution theory, and omits others entirely, such as any formalised theoretical interface to the software side of the (data/software) coin. (eg: stored procs).

Normalisation of tables in order to pedantically avoid the use of nulls as though they were some form of an alien life form. Date approaches complexity ad nauseum but offers no simple solutions, and cannot, because of his data centric view of a data _processing_ environment.
