Abstract
Today's rapidly changing, global, competitive business environment requires that an enterprise optimize its operations and leverage its data, information, and knowledge resources better than ever before. the result is an ever-increasing demand for data, information, and knowledge about the enterprise, its operations, and about its customers, suppliers, and business partners. the database management system is the key component of the information systems infrastructure of the modern enterprise that is focused on meeting this demand. the database management system is an organized store of the enterprise' data that provides ever-increasing capabilities for adding value to data by turning data into information; by turning this information into knowledge; and by sharing data, information, and knowledge securely throughout the enterprise.
