The emphasis is on the end result of the manner rather than the technique itself – the ends as an alternative than the means. This contrasts to the ancient way of programming, in which the user had to describe the statistics gathering step-by-step.

SQL teaches database users how to pleasant phrase their questions in order to receive the fastest, most accurate solutions from the database.
