Download Qizx/open

Qizx/open was the first version of Qizx and has been available as an open-source product since 2003.

QIzx/open fully implements the XML Query language, but it is fairly different than Qizx in terms of XML data access: basically it has no persistent store and no indexing capabilities, therefore it must always parse XML documents into memory before querying and processing.

However Qizx/open can be quite fast for querying on medium size XML collections as shown in this benchmark.

Qizx/open should not be regarded as a database engine, but simply as an XML Query interpreter [See the product comparison table].
