Headline

A query that aggregates intermediate results

Description

Queries may be arbitrarily complicated in how they extract data from given data. An aggregation is relatively simple and regular in so far that it may be understood as extracting data components from compound data and aggregating those intermediate results often with the help of a monoid.
