Rule-based query optimization in spatial databases
Michał Lupa, Adam Piórkowski · 2012
This article addresses how to optimize queries in spatial databases. Authors as mainstream considerations adopted to optimize adjustable speed performance which allows queries on the stage of their development. The result of the study are the observations in the form of proposed rules of optimization, where the effectiveness is verified experimentally. Proposed three methods for decomposition of queries into a less time-consuming computationally. The first is to replace spatial functions in a Boolean search. In the second case, the decomposition property of communication used in the context of the function sum. The third property concerns the identification of communication in terms of joint function.
