# Relation construction

☞ This page belongs to resource collections on Logic and Inquiry.

In logic and mathematics, **relation construction** and **relational constructibility** have to do with the ways that one relation is determined by an indexed family or a sequence of other relations, called the *relation dataset*. The relation in the focus of consideration is called the *faciendum*. The relation dataset typically consists of a specified relation over sets of relations, called the *constructor*, the *factor*, or the *method of construction*, plus a specified set of other relations, called the *faciens*, the *ingredients*, or the *makings*.

Relation composition and relation reduction are special cases of relation constructions.
