In Django, there is three possible inheritance styles
* Abstract base classes : This style is used when you only wants parent’s class to hold information that you don’t want to type out for each child model
* Multi-table Inheritance : This style is used If you are sub-classing an existing model and need each model to have its own database table
* Proxy models : You can use this model, If you only want to modify the Python level behavior of the model, without changing the model’s fields
