Sedna is a native XML database management system. It provides a full range of core database services - persistent storage, ACID transactions, security, indices, hot backup. Flexible XML processing facilities include W3C XQuery implementation, tight integration of XQuery with full-text search facilities and a node-level update language. In addition Sedna supports built-in facilities for processing non-XML data such as SQL connectivity and extensibility via external functions.

Sedna is developed by [http://modis.ispras.ru MODIS] team at [http://www.ispras.ru Institute for System Programming (ISP RAS)] . It is distributed under open source Apache License 2.0.

History

[http://modis.ispras.ru/sedna/index.htm Sedna XML Database] has started out in 2003 as an R&D project in the [http://www.ispras.ru Institute for Systems Programming of the Russian Academy of Sciences] . It quickly passed the stage of a prototype system and evolved into a fully functional native XML database management system distributed under open source license. From inception, it has been designed to handle large databases efficiently without much tuning: hence it does not require a schema to load your data and can execute queries with adequate performance even when the developer has not created any indexes. Sedna also has a couple of innovative features, such as XML Triggers and a version-based transaction processing scheme.
