The advertising activity for the events organized by Pure Entertainment: There are different methods or types of advertisements undertaken at Pure Entertainment such as through distribution of flyers or posters an also through other media such as newspapers, television or radio. One of the equines questions that Pure Entertainment wants to address is if an advertisement type is more cost effective than another. 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. At the end of each financial year Pure Entertainment distributes commissions to the promotion outlets based on the number of tickets they have sold. The percentage commission paid to each outlet for each event they have promoted over the past 10 years is stored in a spread sheet. 2 Pure Entertainment Invoice No: Invoice Date: Client Company Name: Client Address:

Not only will it compromise the efficiency of their operational database, they also wish to incorporate their flat file data into their analysis. They have decided to commission a data warehouse to assist them in addressing the following business questions: 0 What type of entertainment events are the most popular? Has this always been the case or has there been a shift in recent years?
Are there certain times of the year when more events are held? Are certain types of events more common at particular times of the ear? Which ticket promotion outlets sell the most tickets? Does this vary across different months or event types? Who is the most popular performer among those singers, actors, entertainers or celebrities in past 5 years (more ticket sales)? What ticket batch sizes minimize the likelihood of outlets having unsold tickets whilst maximizing profit? What outlets sell more of the different ticket types? For which clients have we provided the most event tickets? How much do we make a year out of our top 5 clients? What ticket types most often sell to full capacity? What are the best ratios of the efferent ticket types for sustained profit mastication? Which venue sections, rows, and groups of seat numbers sell the quickest and to full capacity? How can the ticket types be allocated to venue sections, rows, and groups of seat numbers, such that sustained profit is maximizes? How much commission did we pay to promotion outlets in the last financial year? How does this compare to the past 5 years? What is the main location of those people (customers) purchasing tickets online? What event types are they attending? What ticket types are they purchasing?
