Exercise No. 36: Budget Rental Service (apa)

The following cube stores data about the Budget car rental service.

Cars are rent to customers who can be classified into customer groups (private, business, etc.). There's an option to rent a driver for the car as well. The car is serviced by a garage and belongs to a branch of the Budget car rental service. This branch belongs to the nationalwide operating Budget car rental service

We have five dimensions with the following hierarchical structure:

Table A.21.5.1 - the Budget car rental service

Please build the Aggregation Path Array and assume the following end-user requirements:

1) "a roll up by the time dimension starting at weeks for each customer group independent of the driver, the garage the car is serviced and the branch"

2) "a daily report for each combination of driver and branch, independent of the customer and the garage"

3) "a weekly report for each garage, irrespective of the customer, the driver and the branch"

Select the corresponding cells in the APA and choose the cubes to materialize, then highlight the derivatives of those cubes.
