Descripción
The efficiency and performance of database systems is substantially affected by many decisions which are required throughout the development stages. Unfortunately, the impact on performance of many design alternatives is not yet well understood. In this paper we present an analytical performance model of database systems that provides a means of quantitative comparison of design alternatives. Four levels of abstraction are distinguished for design choices and related performance measures. We describe the design and implementation of a specialization of our general layered model to SYSTEM 2000 environments. We report some preliminary results of the validation of the SYSTEM 2000 performance predictor against data measured in an actual operational environment.
