Abstract :
A performance model of buffer management is presented that is appropriate for use in the context of a multilayer database performance model. Some empirical evidence that supports the model´s hypothesis that database page references are Bradford-Zipf-distributed is provided. A validation of the buffer performance model against data from a real-life environment is reported. Overall, the database buffer management model proposed has accuracy commensurate with that of the other components of multilayer database performance models, yet it does not require extensive parametrization or excessive computation
