Oracle has acquired Sleepycat Software, makers of the open-source BerkeleyDB embeddable database engine.

As you may know, BerkeleyDB is essentially a library to which applications can make function calls, vs. issuing SQL queries to a standalone database server. Java and XML editions are also available.

Most important, as CEO Mike Olson notes in his blog about the acquisition, "We have no plans to change
the open source strategy that Sleepycat pioneered, and that has been so
successful for us. The Berkeley DB products will continue to be
distributed under both open source and proprietary licenses."
