Through its acquisition of Sun Microsystems in 2010, Oracle also became the steward of many other important and long-running open source projects such as the Java programming language and the MySQL relational database, introduced in 1995. The acquisition of Sleepycat Software, brought the open source Berkeley DB key/value store.
