(c) Web- base database systems: The outgrowth is on from the 1990s till the present term. These systems are found on the phenomenal reach of the Internet, XML-based systems, tissue technology and web mining. 1980 till Today 1960-1970 1970-1980 2000 onwards Fig 1.2 Development of Database Management System The latest trend is the integrated information systems based on the above three which paved the way for revolutionary development in decision-making in the corporate world.
