\acrshort{sql}, or unabbreviated, \acrlong{sql}, is a \gls{declarative} programming language, used to describe and operate on databases.

This is is the point to mention \hlhref{https://xkcd.com/927/}{xkcd standards comic}, because, as is the case with almost any standard,
people deviate from it and new standards form.

Even though \textit{most} \acrshort{sql} databases support the standard SQL operations, many have added a lot of features on top.

\sql\ is split up into the query language itself, used to operate on data, as well as the Data Definition Language,
used to create, modify and delete schemas.
