> Why? Databases should never, ever, ever, be used to perform logic, they are datastores, that is it. Your logic goes elsewhere. Stored procedures are the worst "feature" of any database, you are just asking for a hard time debugging, troubleshooting, and increasing the chance that you will fuck up the most valuable part of your system, your data.

You cannot sanely use a database with multiple heterogenous clients without putting logic at least about what valid data should be in it. This is gonna include some “business logic” in practically any real-world system.

Otherwise you have to elevate the same functionality to some gatekeeper-daemon that’ll almost certainly perform far worse, lack features, and be an eternal source of dumb bugs, including, I can just about guarantee, data corruption bugs.
