<A HREF="http://www.infoworld.com/article/06/02/20/75442_08NNsleepyoracle_1.html">Oracle has acquired</A> open source database vendor Sleepycat Software, strengthening its hand in the embedded database market and proving true at least one of the rumors about its plans to buy open source companies. The acquisition extends Oracle's embedded database product line, which also includes Oracle Lite for mobile devices and last year's acquisition TimesTen for high-performance in-memory database applications. Sleepycat's Berkeley DB is embedded in several open source products, including the Linux and BSD Unix OSes, Apache Web server, OpenLDAP directory, and OpenOffice.
