Just to point out, this is MTI reinvented, without any of the Django syntactic magic sprinkled on top. It is exactly equivalent to this: class Address(models.Model): pass class Person(models.Model): name = models.CharField(max_length=50) date_inclusion = models.DateField() class Employee(Person): address = models.ForeignKey(Address) """ The second type of model inheritance supported by Django is when each model in the hierarchy is a model all by itself. Each model corresponds to its own database table and can be queried and created individually. The inheritance relationship introduces links between the child model and each of its parents (via an automatically-created OneToOneField).
