Welcome to Brackit

Coming soon: BrackitMR, the Hadoop extension of Brackit presented at the ADBIS conference on September 2013, will be released on this website soon. Send us an email to get notified!

Brackit is a flexible XQuery-based query engine developed at the TU Kaiserslautern in the context of our research in the field of query processing for semi-structured data. The system features a fast runtime and a flexible compiler backend, which is , e.g., able to rewrite queries for optimized join processing and efficient aggregation operations.

At the moment we support XQuery 1.0 including library module support, the XQuery Update Facility 1.0 and some features of XQuery 3.0 like the new FLWOR clauses group by and count.

As a speciality, Brackit comes with extensions to work natively with JSON-style arrays and records. Another extension allows you to use a special statement syntax for writing XQuery programs in a script-like style.

Sounds interesting? Then have a look at the Getting Started Guide.

BrackitDB is an XML database management system, which is powered by the brackit query engine. Its native XML storage offers advanced indexing capabilities and full ACID transactions. Learn more about it here.

Enjoy!
