Оптимизация запросов к кадастровой базе данных

Abstract

Цель данной статьи анализ оптимальных путей выполнения клиентских запросов. При анализе и перестройке SQL-запросов снижается время их выполнения в десятки, даже в сотни раз. Важность исследования компонента оптимизации определяется тем, что от его развитости критически зависит общая производительность любой SQL-ориентированной СУБД.

The aim of this article analysis the more optimal ways to realized clients SQL needs. If SQL needs are analyzed and changed, the time of realized are increased. The researching component of optimization are important part of research, because each SQL-oriented DBNS common productivity are depend of optimization component maturity.
