If you want something more advanced and fundamental, I'd recommend classic Database System Implementation[0] by Hector Garcia-Molina; Jennifer D. Widom; Jeffrey D. Ullman. It's still relevant. Technologies change, but fundamental principles and algorithms... change order of magnitude slower.

And yes, it's that Ullman.

I took the same course @geedy is speaking of (with him, in fact) and there are two good comparable resources I'm aware of:

(1) Ramon's (excellent!) lecture notes themselves are currently (but not always) available on his website: https://people.ok.ubc.ca/rlawrenc/teaching/404/notes/index.h...

(2) Garcia-Molina, Ullman and Widom's book and courses taught on their work: http://www.amazon.ca/Database-System-Implementation-Hector-G... http://infolab.stanford.edu/~ullman/dbsi.html
