    Databases, where user-supplied calculations can specify a field’s value. Spreadsheets Spreadsheets are not normally called calculators because their main purpose is to organise data in rows and columns, and to automatically update the values of possibly many dependent cells when the value in another cell changes. The calculation features are ...

    Power Query is built on what was then [when?] a new query language called M.It is a mashup language (hence the letter M) designed to create queries that mix together data. It is similar to the F# programming language, and according to Microsoft it is a "mostly pure, higher-order, dynamically typed, partially lazy, functional language."
