The existing methods for performing a join of relations in the parallel column-oriented database system are analyzed. The Laplace–Stieltjes transform is deduced for the time of joining two tables using the nested-loop method, and the variants of this transform are considered for the SE, SD, and SN architectures and different operating modes of the parallel database systems.
