Benefits of Qizx:

bullet Real query speed without effort 

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: simply store your documents and voila. No need to manually define indexes, tweak parameters, or add a new index (and re-index all your database) each time you have to run a new query.

    No need to learn non-portable proprietary functions in order 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.

These pages show some tests 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.

bullet Power
  • Fully compliant XQuery implementation. Built-in support of XQuery Update, XQuery Full-Text, XQuery Scripting.
  • 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 hundreds of gigabytes, with tens of millions documents.
  • Query isolation, ACID transactions (failed updates can be rolled back); hot backup; crash recovery.
bullet 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.
bullet Friendly prices, licenses

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.
