Plone Database

Documentation overview about Plone Database - transactional object database ZODB.

Plone is technology neutral. Plone can interoperate with most relational database systems, both open source and commercial.

However, by default settings, Plone stores its contents in Zope's built-in transactional object database, the ZODB.

ZODB, the Zope Object Database, is a persistent object database system for Python. It provides facilities to write objects to disk automatically, read them in again when they're required by a running program, and cache them.

On the file system, this database is contained in the file Data.fs, normally located in the var directory (for traditional Zope installations) or in var/filestorage directory (for buildout-based Zope installations).
