As queries grow increasingly complex and large data sets are becoming prevalent, Parallel Query Processing, database sizes grow dramatically particularly in Decision Support Systems (DSS) , and OnLine Analytic Processing Systems ( OIAP) which have recently emerged as important database applications. In these systems, performance is a critical issue and speeding up the system has always been an objective but the processing power of individual processors can only handle a small fraction of current applications. As a result, parallel processing is exploited to improve database systems performance. In the thesis we focus on relational database systems and study skew characteristics and their effects on parallel query processing.
