BaseX is a native and light-weight XML database management system and XQuery processor, developed as a community project on GitHub.[1] It is specialized in storing, querying, and visualizing large XML documents and collections.[2] BaseX is platform-independent and distributed under a permissive free software license.

In contrast to other document-oriented databases, XML databases provide support for standardized query languages such as XPath and XQuery. BaseX is highly conformant to World Wide Web Consortium (W3C) specifications[3][4] and the official Update and Full Text extensions. The included GUI enables users to interactively search, explore and analyze their data, and evaluate XPath/XQuery expressions in realtime (i.e., while the user types).


Database Layout[edit]

BaseX uses a tabular representation of XML tree structures to store XML documents. The database acts as a container for a single document or a collection of documents. The XPath Accelerator encoding scheme and Staircase Join Operator have been taken as inspiration for speeding up XPath location steps.[6] Additionally, BaseX provides several types of indices to improve the performance of path operations, attribute lookups, text comparisons and full-text searches.[7]

Project History[edit]

BaseX was started by Christian Grün at the University of Konstanz in 2005. In 2007, BaseX went open source and has been BSD-licensed since then.[8][9]

Supported systems[edit]

The BaseX server is a pure Java 1.7 application and thus runs on any system that provides a suitable Java implementation. It has been tested on Windows, Mac OS X, Linux and OpenBSD.[10] In particular, packages are available for Debian[11] and Ubuntu.[12]
