## AI overview

The second article in a three-part series examines open research problems in transaction-processing database systems as CPU architectures move from multi-core to many-core designs. It discusses limits in existing DBMS architectures and evaluations, and explains why future systems with hundreds or thousands of low-power cores may require different software approaches.
