Answer : It is the number of attributes of its relation schema.

The degree of relationship is also known as "Cardinality". It 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:

one-to-one (1:1)
one-to-many (1:M)
many-to-many (M:N)
