سؤال 31. How can you set up the database in Django?

You can edit mysite/setting.py, a module representing Django settings. By default, Django uses SQLite, which is easy to use and does not require any type of installation.

If your database choice is different, you have to do the following keys in the DATABASE ‘default’ item for matching your database connection settings:

• Engines: You can make the changes to the database using ‘django.db.backends.sqlite3’, ‘django.db.backeneds.mysql’, ‘django.db.backends.postgresql_psycopg2’, ‘django.db.backends.oracle’, and so on.
