How does a database software help business professionals and the operations of the business?

Historical database was simply a set of cards in a draw that referred the reader to other draws to find more information. The reader then had to manually write each set of information down and complete the output information from that. It was long, difficult, costly and frequently information was missed. Now with something as simple as a flat file database business can enter data and build up associated data against each entry. Using quires and reports we can pull back that data in a range of different ways exceptionally quickly and more accurately. By designing new queries we can change how the data is represented and what it tells us. The cost effectivness is huge.
