CONSULTING OPPORTUNITY 10.1 Around the World in 80 Objects Because you have described the advantages of using object- oriented (0-0) approaches, Jules and Vern, two top executives at World's Trend (a mail order supplier of high-quality, fashionable clothing, whose customers place orders by phone, mail, or via their website), would like you to analyze their business using this approach. Here is a Summary of World's Trend Business Activities: 1. When customer orders come in, the item master and the cus- tomer master files are both updated. If an item is out of stock, the inventory control department is notified. 2. If the order is from a new customer, a new record is created in the customer master file. 3. Picking slips are produced for the customer order and sent to the warehouse. 4. A shipping statement is prepared. 5. The process of shipping a customer order involves getting the goods from the warehouse and matching up customer the customer shipping statement, getting the correct customer address, and shipping it all to the customer. 6. The customer statement is generated and a billing statement is sent to a customer once a month. 7. An accounts receivable report is sent to the accounting department. Notice also the series of data flow diagrams in that chapter to help you conceptualize the problem and begin making the transition to Object Think Because you are such good friends with Jules and Vern and because you wouldn't mind getting a little practical experience using 0-0 thinking, you agree to apply what you know and give them a report. Once you have reread the business activities for World's Trend, provide a timely review by completing the following tasks: Use the CRC cards technique to list classes, responsibilities, and collaborators. Use the Object Think technique to list "knows" and corre- sponding attributes for the objects in those classes identified in the previous stage. Write up both steps and fly over to World's Trend head- quarters with your report in hand. Clearly, Jules and Vern are hoping for a fantastic voyage into the new world of object- oriented methods
