 - Each model is a Python class that subclasses django.db.models.Model.
 - Each attribute of the model represents a database field.
 - Django gives you an automatically-generated database-access API; see `Making queries <https://docs.djangoproject.com/en/dev/topics/db/queries/>`__.

+peewee
+------
+
+`peewee <http://docs.peewee-orm.com/en/latest/>`_ is another ORM with a focus on being lightweight with support for
+Python 2.6+ and 3.2+ which supports SQLite, MySQL and Postgres by default. The `model layer <https://peewee.readthedocs.org/en/latest/peewee/quickstart.html#model-definition>`_
+is similar to that of the Django ORM and it has `SQL-like methods <https://peewee.readthedocs.org/en/latest/peewee/quickstart.html#retrieving-data>`_
+to query data. While SQLite, MySQL and Postgres are supported out-of-the-box, there is a `collection of add-ons <https://peewee.readthedocs.org/en/latest/peewee/playhouse.html#playhouse>`_
+available.
+
+PonyORM
+-------
+
+`PonyORM <http://ponyorm.com/>`_ is an ORM that takes a different approach to querying the database. Instead of writing
+an SQL-like language or boolean expressions, Python's generator syntax is used. There's also an graphical schema editor
+that can generate PonyORM entities for you. It supports Python 2.6+ and Python 3.3+ and can connect to SQLite, MySQL,
+Postgres & Oracle
+
+
+
+SQLObject
+---------
+
+`SQLObject <http://www.sqlobject.org/>`_ is yet another ORM. It supports a wide variety of databases: Common database systems
+MySQL, Postgres and SQLite and more exotic systems like SAP DB, SyBase and MSSQL. It only supports Python 2 from
+Python 2.6 upwards.
