Oracle Corporation, the world's largest enterprise software company, specializes in developing and marketing enterprise software products — particularly ERP, CRM, EPM/BI, VCP, GRC, database and middleware management systems. Through organic growth and through a number of high-profile acquisitions (PeopleSoft, JDE, Siebel, Agile, Hyperion, Demantra, Retek, BEA, Sun and others) Oracle enlarged its share of the software market. Oracle subsequently surpassed IBM after its acquisition of Hyperion, BEA , and Sun.

The corporation has arguably become best-known due to association with its flagship Oracle ERP product E-Business Suite and it's database. Oracle also develops, manufactures, markets, distributes, and services database and middleware software as well as applications software designed to help customers manage business data, support business operations, and facilitate collaboration and application development and grow their business operations across 42 industries.

CEO and founder of Oracle Corporation, 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 still retains his role as CEO.
