History

Oracle headquarters front view

When the company started, computer database technology was only starting. Ellison had read^[5] a 1970 paper written by Edgar F. Codd on relational database management systems (RDBMS).^[6] He had also heard about the IBM System R database from an article in the IBM Research Journal by Ed Oates. System R was also based on Codd's theories. Ellison wanted to make Oracle's product compatible with System R, but IBM stopped this by keeping the error codes for their DBMS (DataBase Management System) secret. Ellison co-founded Oracle Corporation in 1977 with Bob Miner and Ed Oates under the name Software Development Laboratories (SDL). In 1979 SDL changed its name to Relational Software, Inc. (RSI).^[7] In 1982, RSI renamed itself Oracle Systems^[8] to make the relation to its main product, Oracle Database, clearer. At this stage Bob Miner was the company's senior programmer. In 1995, Oracle Systems Corporation changed its name to Oracle Corporation.^[9]

Part of Oracle Corporation's early success came from using the C programming language to install its products according to technologist Gerard De Van and Adam Day. This made changing the setup to different operating systems (most of which support C) easier.
