I skimmed through the first edition, the book is heavily biased towards telling you to do everything you can(business logic) in the DB versus doing stuff in application code. Whether that's good or bad, it depends, but the book philosophy is to cram as much as application code you can into the DB, citing performance and less code to write as reasons.
