== Gadfly ==
Gadfly is a simple relational database system implemented in Python based on the SQL Structured Query Language.
Line 72: Line 112:
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

== 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.

== KirbyBase ==

= 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)
 * xBase (http://linux.techass.com/projects/xdb/) - Python interface in plans

== 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-dbm.html dbm],
[http://www.python.org/doc/current/lib/module-gdbm.html gdbm]
in Python Standard Library.

== MetaKit ==
http://www.equi4.com/metakit/python.html

== SQLite ==
 * pysqlite: http://pysqlite.org/
  * Have versions for both SQLite 2 and 3.
 * APSW: http://www.rogerbinns.com/apsw.html
  * SQLite 3 only.
  * Not DBAPI compliant. Focus on wrapping all SQLite APIs.

= 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 ==

http://www.4suite.org/

== xsdbXML ==
http://xsdb.sourceforge.net/

= Object-Relational Mappers =

[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'''

= Special file interface =

 * http://python-dsv.sourceforge.net/ CSV or any separated file (see also PEP:0305)
 * ConfigParser.py - Windows .ini format
 * gzip.py
 * zipfile.py
 * tar
 * pdf http://www.pythonware.com/
 * PyTables
 * [[buzhug|buzhug]]
 * [[SnakeSQL|SnakeSQL]]

Generic Database Interfaces and APIs

  • The Python standard for database interfaces is the Python DB-API (PEP 249) Most Python database interfaces adhere to this standard.

  • Most databases have ODBC support; see the section below on ODBC modules.
  • Java databases usually support JDBC, and can be used from Jython.
  • See also DbApiModuleComparison
