what is ORACLE?
Oracle is a powerful relational database management system that offers a large feature set,which runs on more than 80 platforms. Oracle was the first database product to run on a variety of platforms from micro to mainframe.
Oracle Corporation is an American multinational computer technology corporation that specializes in developing and marketing hardware systems and enterprise software products — particularly database management systems. Headquartered in Redwood Shores, California, United States and employing 105,000 people worldwide as of 1 July 2010,it has enlarged its share of the software market through organic growth and through a number of high-profile acquisitions. By 2007 Oracle had the third-largest software revenue, after Microsoft and IBM.
Larry Ellison, a co-founder of Oracle Corporation, has served as Oracle's CEO throughout its 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 management systems (RDBMS) named "A Relational Model of Data for Large Shared Data Banks".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). In 1982, RSI renamed itself Oracle Systems to align itself more closely with its flagship product Oracle Database. At this stage Bob Miner served as the company's senior programmer. In 1995, Oracle Systems Corporation changed its name to Oracle Corporation.
