In the past (why do I feel so old when I say this?), DBMSs WERE used to implement complex logic. Not just complex business logic, but even authentication, authorization, etc were implement with stored procs, embedded sql, native DB features.

The cycle in tech will shift from one side to another; last decade was a lot of no-sql where all this logic and implementation had to reside on the application side. I'm seeing a shift back to DBs again (e.g. supabase), and the reality is that it's probably a continuum somewhere in-between, depending on your requirements (as always, the answer is "Yes, but it depends").

Remember, these are all "just" tools.
