I've seen people who disagree with that statement and say that having a separate back end component often leads to overfetching and in-database processing is better. I've worked on some systems where the back end is essentially just passing data to and from stored procedures.

It was blazing fast, but working with it absolutely sucked - though for whatever reason the people who believe that seem to hold those views quite strongly.
