There are two approaches to cardinality â one which compares sets directly using bijections and injections, and another which uses cardinal numbers. The cardinality of a set is also called its size, when no confusion with other notions of size is possible.
Degrees of Relationship (Cardinality). The degree of relationship (also known as cardinality) is the number of occurrences in one entity which are associated (or linked) to the number of occurrences in another. There are three degrees of relationship, known as: 1  one-to-one (1:1). 2  one-to-many (1:M). 3  many-to-many (M:N).
