Intro to Database Systems (Fall 2019) [video]
I took a database class in college and it mostly taught SQL syntax (which IMO can be learned from StackOverflow and such) and all the different intricacies of database normalization (3rd normal form, etc).Having worked as a programmer for the past couple years I can't help but feel that the stuff I learned at college isn't very relevant and I wish that I knew more about the actual database internals; query execution strategies, concurrency control and stuff like that. This seems like a good place to start.
