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※
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 keyword indexing system.
History※
eXist-db was created in 2000 by Wolfgang Meier.
eXist-db was awarded the best XML database of the year by InfoWorld in 2006.
The companies eXist Solutions GmbH in Germany. And Evolved Binary in the UK, promote and "provide support for the software."
There is an O'Reilly book for eXist-db which is co-authored by Adam Retter and Erik Siegel.
