Examine the OLAP cube in Figure 9-11. The values in this report (or cube as OLAP reports are called)

are sums of rental revenue of vehicles.

a. Using your intuition and business knowledge, what do you think the value $3,697 means? What do $1,587 and $2,121 mean?

b. State three conclusions that you can make from this data.

c. The principal advantage of OLAP is that columns and rows can be switched and the report values will be recalculated automatically. Explain what would happen if the user of this report were to switch the first column (geographic area) with the third column (brand). You do not have sufficient data to compute values, but explain in words what will happen.
