Qizx/db Product

bullet Whether and why use Qizx/db

bullet Technical specifications

bullet Licensing

Qizx/db can be used under three licenses:

bullet Evaluation key

You can evaluate Qizx/db without size limitations by requesting an evaluation key, valid for three weeks.

bullet Free Engine

Qizx/db is available as Free Engine edition, which has all the features of the commercial product, but is limited in terms of the maximal size of a database (approximately 1000 megabytes of source XML).

bullet Qizx/open

The Open Source version of Qizx has been available since 2003. QIzx/open fully implements the XML Query language, but it is fairly different than Qizx/db in terms of data access: basically it has no persistent storage and no indexing capabilities, so it must first parse XML documents into memory before any processing.
