In 1977, Larry Ellison, Robert Miner, and Ed Oates founded Software Development Laboratories, which was hired by the United States Central Intelligence Agency (CIA) in order to write a new database system based upon SQL. This system came to be known as Oracle. The company changed its name to Oracle Systems Corporation not long thereafter, in 1982.
