Question

Quizplus · Accepted Answer

A unary relationship describes a relationship between instances of the same entity type. It is also known as a recursive relationship because it can be depicted as a loop, where each instance is related to another instance of the same entity type. For example, a "Supervisor manages Employee" relationship can be represented as a unary relationship, where each Employee instance may have a Supervisor who is also an Employee. Thus, option A) is the correct answer.

Option B) composite relationship refers to a relationship where a composite entity is created to represent the relationship between two entities.

Option C) recovering relationship is not a valid term in the context of database design.

Option D) partial relationship describes a relationship where not all instances of one entity are related to instances of another entity.

Option E) transitive relationship describes a relationship where a relationship between two entities is indirectly determined through another entity type.
