1. An inventory control system keeps a file of records about
the stock of goods that a business has on hand (the
inventory) which is one aspect of the state of the business.
2. When items are shipped or received, the state of the
business is affected, and the inventory control system
makes changes about the inventory in the stored records.

• 4. It also prints a report giving the quantity on
hand for each item in inventory, which is a
characteristic of the state of the business.
• Finally, when inventory is low, the system
produces output that causes more inventory to
be ordered, which is another type of business
transaction.

confronting a business. The effect of this force is
seen almost daily in a wide variety of industries.
2-52

• It is often at its strongest during periods of rising
costs or inflation. When airline prices get too
high, peoples substitute care travel on their
vacations. Exp.
• If the customers’ bargaining power gets to
strong, they can drive prices to unmanageably
low level or simply refuse to buy the products or
service.
• If a key suppliers’ bargaining power gets to
strong, it can force the price of goods and
services to unmanageably high levels. 2-53

automatically transfers the file to the
requesting PC

6-228

file names
• Clicking a link automatically transfers the file
from that user’s hard drive to yours
