Sleepycat Software, Inc., awakened to release the latest version of Open Source Berkley DB database. Version 3.3 adds performance enhancements and includes support for high availability and Lineo's Embedix embedded Linux operating system. Berkeley DB runs on UNIX, Linux, Wind River's VxWorks, QNX's RTOS, and Windows 95/98/NT/2000.

Berkeley DB requires no separate database server or administration once embedded in the application. It provides concurrency, transactions, disaster recovery, hot backup, and other critical services. Sleepycat licenses three different Berkeley DB products. All three products are included in the download package.

The three versions are:

• Berkeley DB Data Store: An embedded data store for single-user read-write or multi-user read-only applications. Supports B+tree, hashed, or record-based data storage and retrieval. Does not support transactions or disaster recovery.
• Berkeley DB Concurrent Data Store: Provides all the features of Berkeley DB Data Store, but adds support for multi-user read-write access to the same database. Intended for applications for which updates are infrequent but required.
• Berkeley DB Transactional Data Store: A full-featured embedded transactional store with logging, fine-grained locking, the ability to commit or roll back groups of changes all at once, and disaster recovery. Intended for high-concurrency read-write workloads and for applications that require transactions and recoverability.

Complete source code for Berkeley DB version 3.3 is available for download from their Website now.
