Person Association (PersonAssociation)

A person or organization associated with student or staff member. The concept of Person Associations are sometimes modeled as a type of a person such as contact person, guardian, etc. However, these entities are modeled here as an association to another person rather than as a person.  This is because a logical data model most likely will not model this entity as a separate person from other persons such as parent, primary contact, etc., but rather as a related person.
