Benefits of using Qizx/db:

 Query speed 

Qizx/db is designed from the ground up to perform fast queries, without requiring specific efforts from users.

This page shows some performance 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) and joins.

 Simplicity 

• Simplified administration and configuration. No need for DTD or Schema.
• Queries work at full speed out of the box: there is no need to manually define indexes, tweak parameters, etc.

 Processing power

• Fully compliant XQuery implementation.
• Numerous extensions: indexed full-text, dynamic evaluation, error handling, connection with XSLT.
• User-defined metadata properties on XML documents and collections: this metadata can be queried as fast as other XML data, allowing for example to define custom indexes.
• Access to Relational DBMS in XQuery.
• Really capable of handling databases of several tens of gigabytes, with millions of documents.
• Query isolation, ACID transactions; hot backup; crash recovery.

 Affordable cost

Qizx/db is priced lower than all other comparable commercial products.

 Extensibility

• Simple and powerful Java API with many extension points (pluggable filters, observers, indexing, 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.
