ZODB

Developed by the same people that developed ZOPE, a framework and application server for Python-based apps, ZODB provides an application agnostic database system for Python developers.
ZODB is built on an OODB (object-oriented database), very different from classic relational databases, and somewhat closer to NoSQL databases.

ZODB stores an objects relations map, instead of saving data to tables.

This means data can be queried programatically instead of using an SQL-like language.
