From Joins to Aggregates and Optimization Problems

The course introduces recent development on solving a host of computational problems in the database. The unifying theme underlying this development is the use of the structure of the problem to avoid redundancy in data representation and computation.

Image Description

In-Database Analytics

Scalable techniques for machine learning over databases that exploit the relational structure, push the learning task inside the database query engine, and factorise its computation.
