Benefits of Qizx: Blazing query speed,
easily Qizx is designed from the ground up to perform fast queries,
without requiring specific efforts from users. Queries run at full speed out of the box: you store your
documents and that's it. No need to tweak parameters, to manually
define indexes, to add a new index (and re-index all your database)
each time you introduce a new query... No need to use
non-portable specific functions to benefit from indexes: Qizx has a
powerful query optimizer that directly understands standard
XQuery. - DTD or Schema not required.
- Very simple administration and configuration.
This page shows some speed
measurements made on standard hardware. Qizx shines particularly on the
operations the most useful in practice: full-text search, search by
value (single or combination, range) and joins. Processing power- Fully compliant XML Query implementation. Built-in support of
XQuery Update, XQuery Full-Text.
- Numerous extensions: dynamic evaluation, error handling,
connection with XSLT.
- User-defined metadata properties on XML documents and
collections: this metadata can also be queried at full speed,
allowing for example defining custom indexes.
- Really capable of handling repositories of several tens of
gigabytes, with millions of documents.
- Query isolation, ACID transactions (failed updates can be rolled
back); hot backup; crash recovery.
Liberal licensing, affordable
costThree types of licenses designed to suit all needs: Server License, Site License and a very liberal Developer License which allows royalty-free
deployment of Qizx-based products and applications. A Free Engine
edition allows running Qizx on your servers on XML repositories not
larger than one Gigabyte of XML approximately. Extensibility- Simple and powerful Java API with many extension points
(pluggable filters, observers, indexing, full-text capabilities
(text parsing, stemming, thesaurus, scoring), data import/export,
access control, XQuery module resolving, etc).
- Direct access to Java methods in XQuery (``Java Binding'') to
easily extend the core language with business logic.
