No I don't mean SQL. That's easy.
I mean concepts I'm supposed to learn like data modeling, schema, normalization (whatever tf that is).
I already work with MySQL on a operator standpoint, but I don't have a damn clue on reasons why things are done the way they are in terms of why certain key values exist, and how they relate with other tables.
Apparently there are a bunch of data visualization tools that exist that nobody bothered to tell me about (besides mysql workbench) but of course they talk about network sockets 🤓🤓🤓
I'm gonna plug pleroma or mastodon's database and try to understand why they are arranged the way they are.
