The increasing demands for interactive response time from the users makes query performance one of the central problems of data warehouse systems today. Performance is an important quality aspect of data warehouse systems. Predicting the performance of data warehouse systems during early design stages of their development is significant. Software Performance Engineering (SPE) promotes the idea that the integration of performance analysis into the software development process, from the earliest stages to the end, can ensure that the system will meet its performance objectives.
