Sure. You could use a memory-based database.

The Zope 3 functional tests use DemoStorage, and set up a database with 
basic services and a root folder. DemoStorage has a feature where you 
can specify a base storage and a secondary storage. The secondary 
storage is to store any changes to the base storage. This makes it easy 
to remove all changes made by a particular tests, and restore the state 
of the database, by resetting the secondary storage.
