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).
Technologies
- XPath query language
- XQuery 3.1
- XQuery Update 3.0 (W3C)
- XQuery Full Text 3.0 (W3C)
- Support for most EXPath/EXQuery modules and packaging system
- Client-Server architecture with user and transaction management and logging facilities
- APIs: RESTful API, WebDAV, XML:DB, XQJ;[5] Java, C#, Perl, PHP, Python and others
- Supported data formats: XML, HTML, JSON, CSV, Text, binary data
- GUI including several visualizations: Treemap, table view, tree view, scatter plot
Database Layout
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
BaseX was started by Christian Grün at the University of Konstanz in 2005. In 2007, BaseX went open source and is BSD-licensed since then.[8][9]
Supported systems
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]
