News.com reports today that Oracle said Sleepycat’s open-source Berkeley DB database will complement Oracle’s existing line of closed-source databases for embedding within applications. The products differ from Oracle’s flagship enterprise database software used for general business systems.

Also, the purchase of Sleepycat, which has been rumored for weeks, gives Oracle another open-source product to accompany its proprietary database offerings. At an investor conference last week, Oracle CEO Larry Ellison reiterated the company’s strategy to generate revenue from a combination of open-source and proprietary software.
