Zope Object Database



The Zope Object Database (ZODB) transparently persists Python objects in a transactional database. It is included as part of the Zope web application server, but can also be used independently of Zope.

Features of the ZODB include: transactions, history/undo, transparently pluggable storage, built-in caching, and scalability across a network (using ZEO).

ZEO (Zope Enterprise Objects) is a ZODB storage implementation that allows multiple client processes to persist objects to a single ZEO server. This allows transparent scaling, but the ZEO server is still a single point of failure.

A commercial add-on, Zope Replication Services (ZRS), removes the single point of failure, providing hot backup for writes and load-balancing for reads.Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.2 or any later version published by the Free Software Foundation; with no Invariant Sections, with no Front-Cover Texts, and with no Back-Cover Texts.
