Abstract
The article presents a discussion of the optimisation methods involving the modification of query syntax on the example of the use of indexes that served for the application of the methods in practice, and the presentation and analysis of the test results and their comparison. All the queries were made in a Microsoft SQL Server Management Studio 2014 environment, using the AdventureWorksDW2012 test database provided by Microsoft. The object of the research were SELECT queries, which consequently returned the desired set of output data.
