In the 1970s, Lawrence J. Ellison (Larry Ellison) was inspired by a theoretical paper by Edgar F. Codd on relational databases and attempted to create a system compatible with IBM's System R database.
Larry Ellison, Bob Miner and Ed Oates founded the company Software Development Laboratories (SDL) in June 1977. This is where the first version of the database system was created, which was named Oracle. The database was developed for the CIA until 1979. The company was renamed in 1979 to Relational Software, Inc. (RSI) and moved to Menlo Park, California. An Oracle database running on a PDP-11 was sold to Wright-Patterson Air Force Base. The company named the first product version 2, fearing that a version 1 would sell poorly. The company's founder Larry Ellison also chaired the company for a long time until he retired to the board of directors in September 2014.
Oracle V3 for VAX was released in March 1983. The code was rewritten in C. RSI renamed itself Oracle. Oracle V5.1 was released in 1986 and was the first database system to support distributed queries. Oracle went public on March 15, 1986.
1993 saw the release of Oracle's Cooperative Development Environment (CDE) and the introduction of Oracle Industries and Oracle Media Server. Oracle's headquarters moved to Redwood Shores in 1994.
