• This page seems to duplicate ChoosingDatabase, wouldn't it be better to merge shelve and the rest there? -- DanielDittmar DateTime(2003-02-11T23:15:22)

  I don't think so. Now they surely have to be refactored both, but ChoosingDatabase seems to be a good page for one place for categorized comparision to narrow novice's choice while that is merely a catalog. -- MikeRovner DateTime(2003-02-11T16:50:45)

  I seems missed DbApiModuleComparison page. Probably I better combine them with links from both places. -- MikeRovner DateTime()

DBMS interfaces

Things you connect to.

Take a look at http://www.python.org/topics/database/modules.html and http://dmoz.org/Computers/Programming/Languages/Python/Modules/Databases_and_Persistence/.

MySQL

• mysqldb module http://www.mysql.com/downloads/api-python.html

• SnakeDb (http://www.scriptfoundry.com/modules/snakedb/)

PostgreSQL

Oracle

See ["Oracle"] for details, there are two choices:

• dcOracle

Native Python Databases

gadfly

Gadfly is a simple relational database system implemented in Python based on the SQL Structured Query Language. Currently use C-extension module for speed. Pure Python version included. http://gadfly.sourceforge.net/

ZODB

http://www.zope.org/Wikis/ZODB Zope Object DB

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.

Datafiles interfaces

Things you open.

xBase

Which stands for .dbf files interface.BR .dbf files were produced by several old systems like dBase(II,III,IV), Fox(Base,Pro)

dbm

A family of old unix plain hash tables. Has varieties like dbm, ndbm, gdbm, dbmdb185.BR See [http://www.python.org/doc/current/lib/module-anydbm.html anydbm], [http://www.python.org/doc/current/lib/module-dumbdbm.html dumbdbm], [http://www.python.org/doc/current/lib/module-dbhash.html dbhash], [http://www.python.org/doc/current/lib/module-bsddb.html bsddb], [http://www.python.org/doc/current/lib/module-dbm.html dbm], [http://www.python.org/doc/current/lib/module-gdbm.html gdbm] in Python Standard Library.

MetaKit

SQLite

Actualy it's a full-fleged SQL server, but embeddable. No external SQL server required. Think of Gadfly, only faster. http://PySQLite.sf.net

XML Databases or Interfaces

Forest

[http://cvs.infrae.com/forest/ Forest] is a (native) XML database written in Python. It is intended to support fast queries of XML data.

4ODS

Object-Relational Mappers

SQLObject

[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.
