Django Database: The Perfect Solution for Data Driven Chaos!

Django is a popular open-source web framework used for building web applications with Python. It includes a built-in ORM (Object-Relational Mapper) that allows you to interact with your database using Python objects rather than SQL queries.

To use the Django ORM, you’ll need to define your database models in your Django application. Each model is a Python class which subclasses django.db.models.Model. Each model has a number of class variables that represent fields in the model. 

For example, here’s a simple model that represents an individual with a first name and a last name:

from django.db import models

class Person(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)

Once you’ve defined your models, you can use the Django ORM to create, retrieve, update, and delete records in your database. For example, you can create a new person in the database like this:

person = Person(first_name='John', last_name='Doe')
person.save()

The databases listed below are those that Django formally supports:

• PostgreSQL
• MariaDB
• MySQL
• Oracle \sSQLite

There are moreover numerous database backends offered by outside companies.

Django makes an effort to support as many functionalities on all database backends as is practical. Since no two database backends are alike, we had to choose which functionality to provide and which safe assumptions to make while designing the system.

You can use the Django ORM for performing queries on your database to retrieve records.

For example, you can retrieve all people with the last name “Doe” like this:

people = Person.objects.filter(last_name='Doe')

The Django ORM provides a high-level, easy-to-use interface for interacting with your database. It abstracts away the details of SQL queries and allows you to focus on building your application logic.

All project settings, including database connection information, are contained in the settings.py file. 

Django supports other databases and can be configured to function by default with the SQLite database.

Connectivity to a database requires all the necessary information, including the database name, user credentials, hostname, disc name, etc.

Django.db.backends uses MySQL as the backend.

Application and database connections are made via the mysql driver.
