"The degree (or arity) of a relation is the number of attributes n of its relational schema. An example of a relational schema for a relation of degree seven, which describes university students, is the following:
STUDENTS(Name, Ssn, Home_phone, Address, Office_phone, Age, Gpa)"  - Fundamentals of Database Systems 5th edition, Elmasri/Navathe

Commonly, the main three relational degrees are:
Ornary (one relational connection)
Binary (two relational connections)
Ternary (three relational connections)

n-ary (used when there are many connections)
