The modern database systems management paradigm turns a blind eye to the applications environment, except for a few diagrams in Date. That is why you think the contrary is not true.

It's easy to point a finger in the other direction, but in the final analysis examination of contributing causes to the current state of the nation includes the "paradigm" and its incompleteness.

Database systems theory has not evolved to benefit from the management now available through modern database systems. It expresses a 1970's database/application dichotomy, which is unwholesome and unwarranted and totally and completely unrealistic to the facts of operation, administration and management of database systems today.
