We will continue discussing database system internals, based on the same paper of last lecture:
Hellerstein, Joseph, Michael Stonebraker, and James Hamilton. "Architecture of a Database System." Foundations and Trends in Databases 1, no. 2 (2007): 141-259. (PDF)
We will be focusing on query processing, optimization and memory/storage management. This is still an overview of the concepts that we will present in more details in following lectures.
