The py-alumni database is written in Python and can use a variety of databases as its backend (PostgreSQL is recommended). It uses the CherryPy 2.2 web development framework, the SQLObject 0.7.0 Python database wrapper, and the almost-home-grown Pounder HTML templating system. The source code is freely available from the Subversion repository located at http://www.tortall.net/svn/py-alumni/.
Py-alumni is licensed under the terms of the below license (it's a standard "new" (revised) BSD license).
The database was created in 1997 in C using a flat-file "database". It was rewritten in 2000-2001 from scratch in PHP to greatly improve performance and provide more features. In 2005-2006, it was rewritten from scratch in Python using the CherryPy and SQLObject frameworks, again enhancing the feature set.
The last PHP version released by this author was 0.9; later versions (now maintained by a different author) have migrated drastically in feature-set from the original version, but are available at SourceForge.net.
