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[5][6] 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 (W3C)
- XQuery Full Text (W3C)
- Support for most EXPath/EXQuery modules and packaging system
- Client-Server architecture with user and transaction management and logging facilities
- APIs: RESTXQ, RESTful API, WebDAV, XML:DB, XQJ;[7] 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.[8] Additionally, BaseX provides several types of indices to improve the performance of path operations, attribute lookups, text comparisons and full-text searches.[9]
History
BaseX was started by Christian Grün at the University of Konstanz in 2005. In 2007, BaseX went open source and has been under the BSD-3-Clause license since then.[10][11]
Supported systems
The BaseX server is a pure Java 1.8 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.[12] In particular, packages are available for Debian[13] and Ubuntu.[14]
