Specifically, BankWorld has in excess of 8000 Terabytes (8 million gigabytes) of online storage containing last year’s credit card purchase history. This data is the raw point-ofpurchase information but is totally unsorted. Each item contains the business ID number, customer account number, date, and amount. BankWorld’s internal marketing department proposes to mine this historical data and organize it in ways that will enable BankWorld to earn additional revenue.
