Ticket Sales System The NewCairo Theater Ticket Office keeps track of Customer, productions, performances, and seats. The NewCairo Theater likes to keep track of their Customer so they can notify them of upcoming events, and identify those who frequently support the theatre. Information kept on Customer include first and last name, street address, city, state, zip code, cell phone number, and email address. For the purposes of a computerized system, a unique patron number will need to be created. With regard to productions, the NewCairo Theater maintains information on the name and type of the production, such as play or concert. With respect to performances, the theatre tracks the date of the performance and whether it is a matinee or evening performance. A production can, and usually does, have multiple performances, and can have both a matinee and evening performance on the same date. The theater has a total of 602 seats. Each seat is available for each performance. The seats are in four categories, and the seat numbers are assigned as shown in the following table category price Orchestra $65 00 Mezzanine $55.00 Seat number A1-A30, B1-B30, C1-C30 D1-D30, E1-E30, F1-F30 G1-30, H1-30, 11-30, 31-30 K1-30, L1-30, M1-30, N1-30 AA1-30, BB1-30, CC1-30 DD1-28, EE1-24, F1-24 X1-16 Balcony $40.00 Box $85.00 When a Customer calls or stops by to reserve a ticket, their name, address, and contact information is recorded, if they are not already in the files. The Customer can then select the performance, including the date and whether it is matinee or evening. The Customer then selects their seats from those available for a particular performance. The ticket thus identifies a specific seat for a specific performance. Appropriate and user-friendly data entry/edit screens need to be created to enter and edit information for Customer and performances, as well as ticket sales for a specified seat selection. The system should generate a report of seats sold or available for a particular performance, and should be able to show the seats purchased by a patron (based on name or patron number) for a specific performance.
