Draw a use-case diagram and a set of activity diagrams for the following system. Of-the-Month Club (OTMC) is an innovative young fi rm that sells memberships to people who have an interest in certain products. People pay membership fees for one year and each month receive a product by mail. For example, OTMC has a coff ee-of-the-month club that sends members one pound of special coffee each month. OTMC currently has six memberships (coff ee, wine, beer, cigars, fl owers, and computer games), each of which costs a diff erent amount. Customers usually belong to just one, but some belong to two or more. When people join OTMC, the telephone operator records the name, mailing address, phone number, e-mail address, credit-card information, start date, and membership service(s) (e.g., coff ee). Some customers request a double or triple membership (e.g., two pounds of coff ee, three cases of beer). Th e computer game membership operates a bit diff erently from the others. In this case, the member must also select the type of game (action, arcade, fantasy/science fi ction, educational, etc.) and age level. OTMC is planning to greatly expand the number of memberships it off ers (e.g., video games, movies, toys, cheese, fruit, and vegetables), so the system needs to accommodate this future expansion. OTMC is also planning to off er three-month and six-month memberships.
