7. Computers in Business, Retail, and Delivery
Data mining
Package tracking
Forecasting models
Business around the world is conducted on computers. Information is stored in enormous databases. To make meaning of all that data, businesses use a process known as data mining to spot trends.
In addition to inventory control systems helping managers figure out how much merchandise they need to order to replace stock that is sold, data mining opens the door to more detail.
Data mining is the art of combining huge volumes of raw data into views that provide insight.
Some businesses use package tracking with wireless Bluetooth technology.
Computers assist businesses with predicting sales and inventory levels.

8. Computers in the Arts Create Web sites Digitize dance movements
Produce computer-generated art
The creative arts have also been enhanced by computers. Artists communicate and collaborate across oceans. Writers and editors complete their work together from across the country. New forms of graphic arts and cinematography are introduced every day—globally and immediately. Even dance has been enhanced with the computer.
