Abstract EN
One of the ways to increase work output of the applications connected with database is optimization of queries to database tables.
Importance of query optimization issue increases with growth of records number to decades and hundreds of thousands tables which the query is referring for.
There are various recommendations on troubleshooting of queries performance deceleration.
However, there are no results of experimental investigations on effectiveness of applying other recommendations given in scientific literature.
The authors have conducted numerical experiments for investigation of recommendations, both existing and proposed by the authors, to determine the quantitative values of effectiveness of applying recommendations.
A number of recommendations are illustrated by means of examples of applying recommendations including several alternative variations.
The work describes differences in effectiveness of applying recommendations in different systems of database management considered in this article.
The work describes relative values of effectiveness of applying recommendations compared with source queries.
As a result of article, the authors have developed the algorithm of query text analysis and applying recommendations.
Investigation results expand knowledge on practical applying both known and new recommendations for optimization of queries to database tables.
The article has practical orientation and it is methodically useful for first time programmers in a field of structured queries language.
