This article analyses the process of data warehouse query execution based on star schema in parallel database system (PDS). Laplas-Stiltes transform (LST) is produced for execution time of such query. Different types of this transform and corresponding averages of distribution for different architecture types of parallel database systems are reviewed. The practical example is analyzed.
