Database Support

All XWiki pages are saved in a relational database for better efficiency. This allows XWiki to be fast and scalable. It also allows you to use the Programming features to perform queries in your pages on any data contained in other pages.

Theoretically XWiki supports the same databases Hibernate supports. This means that if you provide the correct Hibernate mapping file all those databases should work fine with XWiki.

More specifically the XWiki Development Team officially supports a subset of all those databases.
