Berkeley DB, the most widely-used embedded data management software in the world, is open source and runs on all major operating systems, including embedded Linux, Linux, MacOS X, QNX, UNIX, VxWorks and Windows. Berkeley DB delivers the core data management functionality, power, scalability and flexibility of enterprise relational databases but without the overhead of a query processing layer.

Combined with the stability and lower support cost of open source code, Berkeley DB offers many advantages, including: Zero administration cost — eliminates the need for a DBA; Smaller footprint (less than 500Kb); Simplicity of integration into an application; More speed and higher performance; Less complexity and more reliability.
