What type of database is used by default in Django?

By default, Django uses the SQLite database.

This is an embedded lightweight relational database in Python that does not require a separate server and is ideal for development and testing.

In the settings.py configuration file, it looks like this:

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

For production, more powerful DBMS such as PostgreSQL or MySQL are usually chosen.
