Description

Computer science has long been considered to emphasize three different perspectives: mathematics, science, and engineering. Mathematics appears in computer science through mathematical formalism, mathematical theories, and algorithms, which are ultimately mathematical objects that can be then expressed as programs, and vice versa. Engineering, which is concerned with making things better, faster, smaller, and cheaper, is prevalent in computer science. Science may be defined as developing general, predictive theories that describe and explain observed phenomena, and evaluating these theories, say via hypothesis testing. While the database field has some very strong mathematical and engineering work, the scientific perspective has been much less prominent.

This project takes a scientifically rigorous approach to an area previously dominated by the engineering perspective, that of database query optimization. Our goal is to understand cost-based query optimizers as a general class of computational artifacts, to come up with insights and ultimately with predictive theories about how such optimizers, again, as a general class, behave.
