Database Systems

Database Management Systems

During the Machine Age, the measure of power was heavy iron typified by cannon, locomotives and rolling mills. In the Information Age, the measure of power is the depth, timeliness and accessibility of knowledge. Communication bandwidth has become more crucial than shop floor capacity. Without the ability to communicate by telephone, e-mail or fax an organization is deaf and dumb. Without access to the database, an organization is blind. Because every firm is now directly or indirectly reliant on computer software, every decision point in the enterprise is an interface point between workers and information systems. The alignment of the information flows with workflows distributed throughout an organization is known as enterprise computing. In an information-intensive business environment, knowledge is power. Competitiveness pivots on how effectively information systems enable management and staff to gain advantages. The single most important requirement for commercial power is the ability to transform operational data into tactical information, and ultimately into strategic knowledge. The main resource that fuels this power is the corporate database. More>>
