Native Python Databases

Gadfly

Gadfly is a simple relational database system implemented in Python based on the SQL Structured Query Language.

http://gadfly.sourceforge.net/

SnakeSQL

SnakeSQL is a pure Python SQL database written to remove the dependence of the Python Web Modules on 3rd party drivers for non-Python databases like MySQL but designed to be a useful database in its own right.

http://www.pythonweb.org/projects/snakesql/

ZODB

Zope Object Database.

• http://www.zope.org/Wikis/ZODB/FrontPage

• DirectoryStorage: http://dirstorage.sourceforge.net/

• PGStorage: http://hathawaymix.org/Software/PGStorage

Durus

Durus is a persistent object system for applications written in the Python programming language. Durus offers an easy way to use and maintain a consistent collection of object instances used by one or more processes. Access and change of a persistent instances is managed through a cached Connection instance which includes commit() and abort() methods so that changes are transactional.

Pypersyst

Pypersyst provides fast, reliable, and flexible object persistence with a small footprint, suitable for embedding in other Python applications.

http://pypersyst.org/

shelve

A [http://www.python.org/doc/current/lib/module-shelve.html shelf] is a persistent, dictionary-like object. The difference with dbm databases is that the values (not the keys!) in a shelf can be essentially arbitrary Python objects -- anything that the [http://www.python.org/doc/current/lib/module-pickle.html pickle] module can handle. This includes most class instances, recursive data types, and objects containing lots of shared sub-objects. The keys are ordinary strings.
