One to One Relationship ER Diagram

A one-to-one relationship in an ER diagram means that one entity instance is associated with only one instance of another entity. This relationship is less common and is used when two entities share a strict dependency. It is represented by a simple line connecting the entities, often with "1:1" notation.
