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 cost

Three 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.
