SECTION 7: Adding data model.
MVC model
MVC model contains all the application logic (business logic, validation logic, data access logic), in addition to the pure view and controller logic.
By MVC, the model can be saved and operation of the application data.

(Ending s) for the data model. This naming convention is to ensure that the controller and database tables linked.
