An Evaluation of Buffer Management Strategies for Relational Database Systems.

Hong-Tai Chou and David J. DeWitt

Summary by Steve Gribble and Armando Fox

One-line summary: A model of relational query behaviour (the query locality set model, or QLSM) is used to motivate a buffer management strategy called DBMIN; QLSM predicts future reference behaviour but separates this prediction from any particular buffer management algorithm.

Overview/Main Points


Minimization of I/Os is key, and buffer management strategies is critical for this task.
