Qizx/db Product
Whether and why use
Qizx/db
Technical specifications
Licensing
Qizx/db can be used under three licenses:
- Server license: use on a single host.
- Site license: use on any number of hosts within a single site.
- Developer license: integration in a software product.
Evaluation key
You can evaluate Qizx/db without size limitations by requesting an evaluation key, valid for three weeks.
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).
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.
