Exercise No. 33: Bus Tour (log)

We will now build a logical model for the "bus tour" case.

We have five dimensions with the following hierarchical structure:

Table L.E.5.1 - Bus tour

"Fee" and "Number of tours" are the key figures in this example. Each customer has an additional attribute "C_cu_add", the customer's address and each bus has an additional attribute "B_bu_age".

Please draw the Classic Star and the Fact Constellation Schema. Then draw the example's dimension tables partitioned and normalized and use them to build a Snowflake Schema!

Solution

This exercise is part of a case study: dfm - apa - log
