What was Oracle Corporation originally called when it was founded in 1977?

Oracle Corporation was originally called Software Development Laboratories when it was founded in 1977.

Larry Ellison, Bob Miner, and Ed Oates established Software Development Laboratories in Santa Clara, California. The company worked on a relational database system inspired by research published by IBM scientist Edgar F. Codd.

The company changed its name to Relational Software, Inc. in 1979 and later adopted the name Oracle Systems Corporation in 1982. It eventually became Oracle Corporation, reflecting the importance of its database products and broader enterprise-software business.

Oracle's history is often simplified by treating Oracle as the original name. The earliest corporate name, however, was Software Development Laboratories, making the full sequence useful for distinguishing the company's founding identity from later branding.
