✅ How to learn Relational Databases?
Hello, sorry this is somewhat off topic for this server, but I think people here will be able to reccomend something. I'm looking to learn a database software, I've settled on postgres and now I want to learn. But I want to go at it from a theory side, not just knowing what SQL commands are what they do, but more the "why" of things. When I studied discrete math in uni we did relations, and I have a vague idea that the relation in relational database comes from that, so I want to explore that side. I hope I'm making sense, if anyone has any suggestions it'll be great. When I look for tutorials etc on postgres, all I get is people teaching how to make tables and how to run queries etc. I did find some things on normal forms, which seemed to be more what I was looking for. Any ideas would be appreciated, thanks!
