eXist-db (or eXist for short) is an open source software project for NoSQL databases built on XML technology. It is classified as both a NoSQL document-oriented database system and a native XML database (and it provides support for XML, JSON, HTML and Binary documents). Unlike most relational database management systems (RDBMS) and NoSQL databases, eXist-db provides XQuery and XSLT as its query and application programming languages.
eXist-db is released under version 2.1 of the GNU LGPL.
Features
[edit]eXist-db allows software developers to persist XML/JSON/Binary documents without writing extensive middleware. eXist-db follows and extends many W3C XML standards such as XQuery. eXist-db 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-db allows users to "drag and drop" XML files directly into the eXist-db database. eXist-db automatically indexes documents using a keyword indexing system.[citation needed]
History
[edit]eXist-db was created in 2000 by Wolfgang Meier.
eXist-db was awarded the best XML database of the year by InfoWorld in 2006.[1]
The companies eXist Solutions GmbH in Germany, and Evolved Binary in the UK, promote and provide support for the software.[2][3]
There is an O'Reilly book for eXist-db which is co-authored by Adam Retter and Erik Siegel.[4]
