N-ary (n Degree)
In the N-ary relationship, there are n types of entity that associates. So, we can say that an N-ary relationship exists when there are n types of entities. There is one limitation of the N-ary relationship, as there are many entities so it is very hard to convert into an entity, rational table. So, this is very uncommon, unlike binary which is very much popular.
Example: We have 5 entities Teacher, Class, Location, Salary, Course. So, here five entity types are associating we can say an n-ary relationship is 5.

Even within a family, you are the son of your father at the same time you are also a sibling of your brother. Similarly, the relationships exist in Database Management (DBMS).
