object-relational mapping layer (ORM)
which can retrieve and modify Python application data from
relational databases such as SQLite, PostgreSQL and MySQL. It has been under active open source development for over 14 years, since before 2003.
SQLObject has been around for a long time as an open source project but unfortunately there are not that many tutorials for it. The following talks and posts will get you started. If you take an interest in the project and write additional resources, file an issue ticket so we can get them added to this list.
This post on Object-Relational Mapping with SQLObject explains the concept behind ORMs and shows the Python code for how they can be used.
Ian Bicking presented on SQLObject back in 2004 with a talk on SQLObject and Database Programming in Python.
Connecting databases to Python with SQLObject is an older post but still relevant with getting started basics.
