BaseX is a light-weight, high-performance, and scalable XML database system and XPath/XQuery processor, including full support for the W3C Update and Full Text extensions. An interactive and user-friendly GUI frontend gives you great insight into large XML data instances. It is platform independent and works out of the box.
Database locking: updates on different databases can now be executed in parallel and won't lock your read-only queries anymore. XQuery: when errors are raised, the full stack trace is now returned; the EXPath Geo Module, Fetch Module, and HTML Module have been added; and the Validation, XSLT, Database, and Profiling Modules have been updated. In the GUI, error messages are now clickable and linked with the text editor. Trace/profiling output is redirected to the info view in real-time
