ShirtCo is trying to determine who was its biggest customer, as measured by total units sold, in 1998. Once ShirtCo determines which customer was responsible for the maximum level of total unit sales, the company would then like to know the breakdown of this customer’s 1998 total expenditures by product and channel. Using the database given in the file P4_25.MDB, construct pivot tables that would provide ShirtCo with the desired information. Summarize your findings.
