Exercise No. 22: Travel Booking (log)

We will now build a logical model for the "travel booking" case.

We have four dimensions with the following hierarchical structure:

Table L.E.46.1 - travel booking

There is only one key figure in this example, "costs". Each customer has an additional attribute "C_cu_add", the customer's address and each travel has an additional attribute "TR_tr_des", the description of a travel.

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
