Django | ORM

ORM stands for Object-relational Mapper. Instead of interacting with the database by writing raw SQL queries and converting the data returned from the query into a Python object, ORM allows us to interact with the database using objects of our model class. So, we just interact with our models and ORM converts these changes into SQL queries based on the database we are using, e.g., SQLite.
