A [http://www.python.org/doc/current/lib/module-shelve.html ''shelf''] is a persistent, dictionary-like object.

This includes most class instances, recursive data types, and objects containing lots of shared sub-objects. The keys are ordinary strings.

[http://sqlobject.org SQLObject] is an object-relational mapper. It allows you to translate
RDBMS table rows into Python objects, and manipulate those objects to
transparently manipulate the database.

[http://orm.nongnu.org/ ORM] ([http://freshmeat.net/projects/orm/ Freshmeat entry]) The Object Relational Membrane is a Python package that provides the functionality of an object relational layer like EJB or other persistence storage systems. It is a thin compatibility layer between SQL table layouts and Object Oriented Python. While providing a good deal of functionality, it tries to be as small and simple as possible. It works with PostgreSQL and MySQL.

QLime ([http://freshmeat.net/projects/qlime/ Freshmeat entry]) Easy to use, transparent data access to relational databases or other data sources. See examples here: http://www.qlime.org/example.rst '''Note: qlime.org does not currently provide the QLime site'''
