database default code in settings django

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'mydatabase',
    }
}

Here is what the above code is Doing:
1. We’re using the default database engine, which is sqlite3.
2. We’re using a database named mydatabase.
3. We’re not using a user name or password.
4. We’re not using a host name.
5. We’re not using a port number.
