Oracle Corporation specializes in developing and marketing enterprise software products — particularly database management systems. Through organic growth and a number of high-profile acquisitions, Oracle enlarged its share of the software market. By 2007 Oracle ranked third on the list of largest software companies in the world, after Microsoft and IBM. Subsequently it became larger than IBM after its acquisition of Hyperion and BEA.
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.
