Oracle Corporation (NASDAQ: ORCL), an American multinational corporation, specializes in developing and marketing enterprise software products, particularly database management systems. The corporation has arguably become best-known due to association with its flagship Oracle database. The company also builds tools for database development, middle-tier software, enterprise resource planning software (ERP), customer relationship management software (CRM) and supply chain management (SCM) software.
Founded in 1977, Oracle has offices in at least 145 countries around the world. As of 2008 it employed more than 70,000 people worldwide. As of 2005 it ranked as the world's second-largest software company by revenue.
The founder and CEO, Larry Ellison, has served as Oracle's CEO throughout the company's history. Ellison also served as the Chairman of the Board until his replacement by Jeffrey O. Henley in 2004. Ellison retains his role as CEO.
Ellison took inspiration from the 1970 paper written by Edgar F. Codd on relational database systems named "A Relational Model of Data for Large Shared Data Banks". He had heard about the IBM System R database from an article in the IBM Research Journal provided by Ed Oates (a future co-founder of Oracle Corporation). System R also derived from Codd's theories, and Ellison wanted to make his Oracle product compatible with System R, but IBM stopped this by keeping the error codes for their DBMS secret. Ellison co-founded Oracle Corporation in 1977 under the name Software Development Laboratories (SDL). In 1979 SDL changed its name to Relational Software, Inc. (RSI). In 1982, RSI renamed itself as Oracle Systems to more closely align itself with its flagship product Oracle Database. At this stage Robert Miner served as the company's senior programmer.
