Each day, computers help millions of people do the job more efficiently. For example, they can help managers decide on a future course of action, and they can then help with the follow-up checks on performance to see if planned goals are being achieved. By using accurate and timely facts supplied by database management software, a manager can do a better job of identifying problems and opportunities. The facts retrieved (检索；使恢复 ) by such software can then be manipulated by a spreadsheet package to help the manager plan to alternate courses of action.
