I’ll be honest, I don’t know a lot about databases, but Atomiticy comes up a fair bit in the web apps I write, as does Consistency in terms of designing data models that can’t go wrong, or trying to encode domain structure into data models to use the Consistency guarantees that Postgres gives us. Isolation is pretty important in general, and easy to reason about from a web app perspective, with requests being isolated from each other at the database level, I rely on that all the time, and Durability doesn’t come up a load, but that’s because I haven’t had to do any sort of disaster recovery. I don’t think it’s essential to know this, but I’d be surprised if a web dev interviewed with us and didn’t know at least the basic version I’ve given above.
