Create an activity diagram and a set of detail use-case descriptions for the following system. Of-the-Month Club (OTMC) is an innovative young firm 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 coffee-of-the-month club that sends members one pound of special coffee each month.

OTMC currently has six memberships (coffee, wine, beer, cigars, flowers, and computer games), each of which costs a different 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., coffee). Some customers request a double or triple membership (e.g., two pounds of coffee, three cases of beer). The computer game membership operates a bit differently from the others. In this case, the member must also select the type of game (action, arcade, fantasy/science fiction, educational, etc.) and age level. OTMC is planning to greatly expand the number of memberships it offers

(e.g., video games, movies, toys, cheese, fruit, and vegetables), so the system needs to accommodate this future expansion.OTMC is also planning to offer threemonth and six-month memberships.
