10/2/2002 - Sleepycat Software, developers of the most widely deployed embedded database engine in the world, announced the release of version 4.1 of Berkeley DB, the award-winning data management system. Version 4.1 adds a range of new features including enhanced security, failover and data throughput on multi-processor computing systems.
The latest version of Sleepycat's popular High Availability solution means customers can keep using an application despite network crashes, power loss or any other system failure. The security enhancements keep data files secure even if hackers gain physical access to the files. Users will see overall performance increases because current systems can do more work without the cost of additional hardware.
"Our customers demand the best in reliability and security for their data," said Michael Olson, president and chief executive officer at Sleepycat Software, Inc. "Encryption and high availability provide our customers with the knowledge that their data is completely secure and always available for their 365/24/7 applications."
Berkeley DB High Availability version 4.1 adds new security features, including encryption that employs the Advanced Encryption Standard (AES) to improve data security. The new encryption support protects applications from an attacker obtaining physical access to Berkeley DB databases. Version 4.1 also includes support for database page checksums to allow detection of database corruption caused by hardware or software failures. There have also been substantial improvements to the shared memory buffer pool in order to improve concurrent throughput and provide better scalability on multiprocessor machines.
Sleepycat's High Availability solution uses a technique called "replication" to keep multiple copies of a database, stored in different places, up to date. In the event of a hardware or application crash that causes one of the copies to fail, applications can use the remaining copies to continue operating without interruption.
Berkeley DB is a core part of the infrastructure of the Internet, with customers deploying mission-critical services including messaging, directory management, calendaring, naming and routing, and more. In addition, Berkeley DB is a crucial part of embedded systems in the fast-growing markets for storage devices and telecommunications systems, among others.
Berkeley DB's source code may be downloaded for evaluation and development. Documentation and licensing information are also available on the web site.About Sleepycat Software
