The type of entity which resolves a many to many relationship is called a(n) _____
The type of entity used to resolve a many-to-many relationship in a database is called a composite entity.
The key to resolve a many-to-many relationship between the entities is to separate them and create two one-to-many relationships between them with a third intersect entity. This intersect entity is referred to as a composite entity, also known as associative entity. It acts as a bridge that handles many-to-many relationships.
The composite entity contains attributes from both the main entities and performs only one function that is providing an indirect relationship between the two entities in a many-to-many relationship. The primary key of the composite entity is composed of multiple attributes inherited from the entities that it relates to.
In many-to-many relationships, more than one record in a table has a relationship with more than one record in another database table. In simple words, multiple records in a table are linked with multiple records in another table. For example, students and courses are associated with a many-to-many relationship, such as a student can enroll in many courses as well as a course can have many enrolled students.
Such relationships are tricky to represent in the database. To solve the problem, entities in a many-to-many relationship require to be linked in a special way through a composite entity.
