database default code in settings django

# settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / "db.sqlite3",
    }
}

• The DATABASES setting in the Django settings file is a dictionary that defines the database configuration.
• The key 'default' indicates that this configuration is the default database for the Django project.
• The 'ENGINE' key specifies the database engine to use. In this case, it's set to 'django.db.backends.sqlite3', indicating the use of the SQLite database engine.
• The 'NAME' key specifies the name of the database file. BASE_DIR is a variable that represents the base directory of the Django project, and / "db.sqlite3" specifies the relative path to the SQLite database file. ```
