---------------

      Zope objects are stored in a high-performance transactional
      object database known as the Zope Object Database (ZODB). Each
      Web request is treated as a separate transaction by the object
      database. If an error occurs in your application during a
      request, any changes made during the request will be
      automatically rolled back. The object database also provides
      multi-level undo, allowing a site manager to "undo" changes to
      the site with the click of a button.  The Zope framework makes
      all of the details of persistence and transactions totally
      transparent to the application developer.  Relational databases
      which are used with Zope can also play in Zope's transaction
      framework.
