| A department store company with stores in 11 cities is planning to install a network so that stores can transmit daily sales by item to headquarters and store salespeople can fill customer orders from merchandise held at the nearest store. Management believes that having daily sales statistics will permit better inventory management than is the case now with weekly deliveries of sales reports on paper. Salespeople have been asking about online inventory availability as a way to retain the customers that now go to another company's stores when merchandise is not available. The planning committee anticipates many more applications so that in a short time the network would be used at or near its capacity. The planning committee identified several applications that would make the company's stores more competitive. One was an on-line gift registry system for customers such as those about to be married. The system would then allow other customers in any of the company's stores to view the information listed in the registry. Once purchased, an item would be deleted from the list. In order to maintain adequate security, the system should have the following restrictions on access: A. Customers have read privileges; salespeople have update privileges. B. Customers and salespeople have update privileges. C. Customers have update privileges; sales-people have read privileges. D. Customers and salespeople have read privileges only. |
