As an example, the Student Of binary relationship form, School: Student, the cardinality ratio of this is 1: N. and that means each of the schools can be mapped to any number of students, however, one student can be mapped to only one school. And various possible cardinality ratios for various types of binary relationships can be 1: N, N:1, 1:1, and M: N.
