Hello,

I am looking for some help to get started on a Use-Case Diagram. I am using the Modern Systems Analysis and Design (8th edition) and focusing on the Petrie Electronics case. I know that I will likely have two actors, the customer and the system but I am not certain about the cases needed. The picture below is for convenience as it is from the textbook and provides more detail about the system.

Similarly, when a customer a by the it must also be recorded, that the customer activity records can be updated to show that the coupon has been used and is now invalid. Send promotions Data about customer activities provide information about what types of products customers tend to buy and in what quantities. This information helps determine what sales promotion materials are best targeted at what customers. Customers who buy lots of video games should receive promotions about games, game platforms, and HD TVs, for example. Generate point Data about customer activities is used to redemption generate coupons for future purchases Those coupons must be made available coupons to customers, either as paper coupons sent in the mail, or they should be made available online, in the customer's private account area. Once created, the customer activity database needs to be updated to show the creation of the coupon. The loyalty points needed to create the coupon must be deducted from the customer's total points. Generate customer From time to time, either in the mail or electronically, customers need to be send reports account reports that show their recent purchases, the coupons they have been issued that have not yet been redeemed, and the total points they have amassed from their purchases
