The tickets for any performance are sold online via the pure website, as well as from promotion outlets, such as retail stores, cafes, restaurants, shops, and boutiques.

Each event may have several performance sessions, such as a play that runs for several days and performs twice per day during this time. Ticket prices may vary between sessions and for various seating positions, or unallocated standing room, for certain events. The company has a centralized operational database to capture their day-to-day ticket sales. The promotion outlets must be supplied with batches of tickets. Those tickets are allocated to each outlet and are not available to be sold online.

To avoid unsold tickets, outlets are initially allocated minimal size batches of tickets and periodically request more batches on demand. If a ticket is sold online, the customer’s details are recorded. Tickets sold via promotional outlets generally do not record the customer details. The database tables that track these processes are given in Appendix A. These tables capture the basic operations of the company including: 0 Ticket sales 0 Ticket distribution to rumination outlets What these tables do not store are details relating to client invoices and promotion outlet commissions.

These details are currently stored in spreadsheets (flat files). Client invoices are printed and sent to the client in the format shown in Figure 1.
