relation
1. <mathematics> A subset of the product of two sets, R : A
x B. If (a, b) is an element of R then we write a R b,
meaning a is related to b by R. A relation may be:
reflexive (a R a), symmetric (a R b => b R a),
transitive (a R b & b R c => a R c), antisymmetric (a R b
& b R a => a = b) or total (a R b or b R a).
See equivalence relation, partial ordering, pre-order,
total ordering.
2. <database> A table in a relational database.
