we are happy to announce the first release of Sedna XML DBMS.
Sedna is a native XML DBMS implemented from scratch in C/C++ and Scheme. It
is designed having the following main goals in mind:
1) support for all traditional DBMS features (such as update and query
languages, query optimization, fine-grain concurrency control, various
indexing techniques, recovery and security)
2) efficient support for unlimited volumes of document-centric and
data-centric XML documents that may have a complex and irregular structure
3) support for the W3C XQuery language in such a way that the system can be
efficiently used for solving problems from different domains such as XML
data querying, XML data transformations and even business logic computation
(in this case XQuery is regarded as a general-purpose functional programming
The first release of Sedna v0.1 is a ready-to-use system that provides the
following fundamental features:
- Support for the W3C XQuery language (partial support for the latest
working drafts of 12 November 2003)
- Support for a declarative update language (it is based on the XQuery
update proposal by Patrick Lehti)
- Native XML data storage structures designed for efficient support for
XQuery and its data model
(no underlying relational or another DBMS). The XML data storage is based on
descriptive schema (also called DataGuide)
- Administration via easy-to-use command line utilities
- Supplied with extensive documentation including Quick Start
Sedna is available for free for commercial and non-commercial usage.
