Overview

The goal of this class is two-fold. First, to introduce you to core database concepts (e.g., data modeling, logical design, SQL) so that you too can build a billion dollar application. Second, to teach enough about database engine internals (e.g., physical database design, query optimization, transaction processing) so you have a good sense of why queries may be running slowly/incorrectly. We will also discuss their relevance to systems used in industry.

The Data Management Seminar invites interesting database researchers and practitioners to speak. Students are invited to join in person or on zoom (if available). We will announce these periodically throughout the semester.
