Database
********

Happyface uses a `PostgreSQL <https://www.postgresql.org/>`_ database to store the data. Each
analysis takes care of its data in the database by creating the appropriate
:mod:`django:django.db.models` and storing the data in the
:meth:`~Happyface4.app_configs.AnalysisConfig.save_data_to_db` call. The
:ref:`status <instance_status>` of the instance is automatically stored in the database.
