Entities have attributes that describe characteristics of the entity. An identifier's value is associated with a specific instance of the entity, not every entity in the data model. Entities can represent either a logical construct or a physical object, depending on the context of the data model. The relationships between entities are not known as attributes, but rather as relationships or associations.
