In this part of the Django tutorials, you will learn about the models and querying a database
in a Django project. First of all you will see how you should create the database tables in Django
using the models.py file and then you will learn how to query the data of the database by modifying
the views, URLs and creating a template file for displaying the result of the query inside a URL.
The example we are going to work on is creating a CRUD application for adding the classmates, seeing
the list of the class students, updating and deleting the list.
