This is the home site for PyORQ.
PyORQ (Python Object Relational binding with Queries) implements persistence
for Python objects using a relational database (RDBMS, e.g. PostgreSQL, MySQL)
for storage. PyORQ uses native Python expressions to describe queries that
can be executed by the SQL backend. On this site you will find:
| Introduction || This brief
introduction to PyORQ describes the key ideas behind its development and gives
an overview of its history. I also tell something about myself|
||This is a new project. A lot has been accomplished, but even more
remains to be done.|
|| The tutorial gets you started with PyORQ. It covers download and
installation, building persistent objects, and writing queries.|
|| The manual for PyORQ is available in several formats and can also
be accessed on-line.|
|| The implementation of PyORQ relies heavily on new features in
Python 2.2/2.3. Here you can find out how PyORQ does what it does.
|| PyORQ can be downloaded directly from the sourceforge

|| Release of Version 0.1 of PyORQ.
This is basically a
technology demo. The purpose of this release is to solicit feedback on the
design and implementation of 'queries as Python expressions'.
The ideas behind PyORQ were first developed when I worked for the astro-wise consortium. I'm particularly
indebted to Danny Boxhoorn for valuable suggestions. Danny also implemented the
Oracle backend for that project.
