Sleepycat's Berkeley DB XML 2.0 Native XML Database

Sleepycat Software Releases Berkeley DB XML 2.0

Major Upgrade of Native XML Database Adds New Support for Emerging XML Data Access Standard and Up To 10x Performance Increase

Emeryville, California, USA. December 14, 2004.

Sleepycat Software, makers of Berkeley DB XML, the leading open source, native XML database, today announced the general availability of Berkeley DB XML 2.0. The major new release includes support for XQuery 1.0, the emerging standard for XML data access, as well as significant performance and usability enhancements.

"This is a major upgrade of Berkeley DB XML and is a significant advancement in native XML database development," said Mike Olson, CEO of Sleepycat Software. "Our new XQuery support benefits customers that have been waiting for a standard for XML databases similar to the SQL standard for relational databases."

"Berkeley DB XML combines the extremely reliable database engine of Berkeley DB with the tremendous ease-of-use of native XML storage," said Steve Bishop, CTO at WildCard Systems, Inc., a leading developer of solutions for electronic payment systems using pre-paid smart cards. "Sleepycat's new support of XQuery gives us greater confidence in moving critical financial transaction support infrastructure to Berkeley DB XML."

"Since AllPeers is a consumer application, it was extremely important for us when choosing a database to find a system that is fast, lightweight, embeddable and needs zero administration," said Matthew Gertner, CTO of AllPeers, developers of a peer-to-peer information sharing platform. "Berkeley DB XML not only meets all of these requirements but also offers excellent native support for XML. The AllPeers platform supports a massive peer-to-peer network for the sharing of millions of files. By storing the XML metadata for each file in Berkeley DB XML, we have achieved much faster time-to-market and a cleaner, more consistent architecture."

New features in Berkeley DB XML 2.0 include:

  • XQuery 1.0 support that allows application portability through complying with the July 2004 draft of the XQuery standard.
  • XPath 2.0 support that allows the selection of a portion of an XML document.
  • PHP API support to easily enable developers using the popular PHP scripting languages to work with XML documents.
  • Improved query performance that can be up to 10 times faster for multi-megabyte XML documents.
  • Ability to control storage granularity of documents (whole documents or nodes) to optimize query performance.
  • XML document streaming into database dramatically simplifies how documents are stored. Documents can now be streamed in from an URI, memory, or file.

"XQuery is clearly the emerging standard for XML databases," said Jerry King, general manager for Stylus Studio, the leading supplier of XML integrated development environments. "The small size and high performance of Berkeley DB XML makes it an ideal XQuery cache for XML developers looking for a fast and lightweight way to store XML documents."
