= Composition of relations
{wiki=Composition_of_relations}
Composition of relations is a fundamental concept in mathematics and computer science, particularly in the fields of set theory, relational algebra, and database theory. It describes how to combine two relations to form a new relation. If we have two relations \\( R \\) and \\( S \\): - Relation \\( R \\) is defined on a set of elements \\( A \\) and \\( B \\). - Relation \\( S \\) is defined on a set of elements \\( B \\) and \\( C \\).
