All of the following questions refer to this scenario:

Jim Stock owns an IT consulting company. Stock is at the Will Call window at the Fyte Theater (FT), trying to pick up tickets he had reserved. However, due to an oversight which turns out to be rather frequent, his tickets were sold to another patron. Fortunately, the manager, Kelly, finds seats which had not been claimed. After talking with Kelly, Stock offers to help the FT avoid this type of problem for a discounted price. He asks you, his intern, to work with Kelly and model the new system.

Productions are booked in advance. Tickets are sold for a specific concert performance of a specific booked production. Productions and specific performances are added up to a year in advance and sometimes the dates or times change or they may be canceled. Bookings are done by Jane, the FT booking manager.

All tickets are for reserved seats. Seats are priced by category (e.g. box, orchestra, main floor, mezzanine, balcony). Tickets cannot be returned or exchanged.

Individual patrons may only purchase tickets online with a credit card and receive an e-ticket. Before patrons can purchase tickets online, they must complete an online profile & account. When patrons buy tickets online, they should first select the production they are interested in. Next, they select the date and time of the particular performance they wish to attend. The system should then display a floor plan showing available seats and allow the customer to select the desired seats. Next, the seats with the total cost are shown to the patron for verification and approval. The patron should have the option to edit the order or accept it by selecting "Pay Now". The customer can only buy tickets for one performance of one production during the same online session.

Corporations can get a corporate patron account. When the corporate rep logs in to the corporate account, they can only purchase tickets a block of tickets for one performance of one production. They select the production they are interested in, then the date and time of the particular performance they wish to attend and the number of tickets they wish to buy. The system then displays a price chart showing the corporate price for a block of tickets in each seating category (box, orchestra, main floor, mezzanine, balcony) and prompts the user to select which price category of tickets they wish. The system then displays the performance and cost information for user acceptance or editing. The corporate account is automatically charged and eTickets are emailed to the corporate user.

Kelly would like to be able to produce a report showing the tickets sold for particular performances and one showing tickets total revenues for each performance.
