BaseX is a native and light-weight XML database management system and XQuery processor, developed as a community project on GitHub. [3] It is specialized in storing, querying, and visualizing large XML documents and collections. [4] BaseX is platform-independent and distributed under the BSD-3-Clause license. [2]

Contents

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

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]
