In the relational world, query languages are typically categorized as
algebraic, mapping, and calculi. Algebraic languages are procedural,
specifying how data is accessed and derived. Calculi are the most
declarative, describing the result. Mapping languages, which includes SQL,
are somewhere in between. SQL describes a mapping between relations. That
is it maps stored relations to externalized relations.
