There are several types of relationships.

  • OneToMany
  • OneToOne
  • OneToNone
  • ManyToNone

A OneToMany relationship has a Set of members and a link to the belongsTo. Each member and the belongsTo has a link back to the relationship. The member links can change.

A ManyToNone relationship has a Set of members and a link to the belongsTo. The belongsTo has a link back to the relationship. The link doesn't change.
