Yes, CMU

The beginner courses are only slides/pdfs, but the "advanced" (it's not that advanced) course has full lectures on youtube.

The manga guide to databases is half decent, but my favorite book is Toon Koppelaar and Lex de Haan's Applied mathematics for database professionals. A pdf version is easily found online.

I also recommend you read Codd's paper A relational model of data for large shared data banks. Read it, look up the words, reread it until you get it. Then read it a few more times.

It's useful to understand hierarchical, network, relational and ER data models, to be able to distinguish them and translate data models between them. The meaning of terms like entity, relationship and relation depend on the particular data model you're using. Every online blog and tutorial will teach you a mismash of concepts mostly based on the old network data model but call it ER modeling. If you want to understand the real entity-relationship model, read Chen's paper The entity-relationship model - toward a unified view of data.

CJ Date's An introduction to databases is like the reference bible, but I'm not sure it's the best starting point.

Don't bother with Wikipedia, it's overcomplicated and not very accurate. Ignore blogs, online tutorials (hurr tutorialspoint), product documentation, etc. Ignore anything that mentions OOP / classes.
