CS267 Spring 2021 Lecture Notes
Topics in Database Systems
Videos of lectures are available.
Below are my lecture notes for the class so far.
They should serve as a rough guide to what was covered on any given day.
Frequently, however, I say more in class than is in these notes.
Also, I tend to dynamically correct typos on the board
that might appear in these lecture notes. So caveat emptor.
