Time estimation of inquiries performance with the correlated subrequests and aggregation operations

U. Grigorev, S. Ostrikov

N. E. Bauman Moscow State Technical University

Abstract: In this article the approach to construction of alternative plans of inquiries performance with the multilevel enclosed correlated subrequests and aggregation operations is offered. Analytical expressions are proved, allowing to estimate time characteristics of these plans, and recommendations at the choice of this or that plan depending on parameters of inquiries and filling of a database are given.
