eXist is an open source NoSQL database and application platform built on XML technology. It is classified as both a NoSQL Document database and a native XML database (and it provides support for XML, JSON, HTML and Binary documents). Unlike most RDBMS and NoSQL databases, eXist provides XQuery and XSLT as its query and application programming languages.

eXist is released under version 2.1 of the GNU LGPL.

History

eXist was created in 2000 by Wolfgang Meier who still is the lead developer as of 2013. In September 2006, it reached version 1.0 and 1.1 (new numbering scheme). In February 2013 it reached version 2.0. Current maintenance activities are on the 2.1.x and 1.4.x versions and new developments are on the 3.0dev version that will be released as 3.0.0.

eXist was awarded the best XML database of the year by InfoWorld in 2006.[1]

eXist is used heavily in the XRX web application architecture.

Features

eXist allows software developers to persist XML/JSON/Binary documents without writing extensive middleware. eXist follows and extends many W3C XML standards such as XQuery. eXist also supports REST interfaces for interfacing with AJAX-type web forms. Applications such as XForms may save their data by using just a few lines of code. The WebDAV interface to eXist allows users to "drag and drop" XML files directly into the eXist database. eXist automatically indexes documents using a keyword indexing system.

Supported standards and technologies
