Exercise No. 45: Pizza Service (log)

We will now build a logical model for the "pizza service" case.

We have five dimensions with the following hierarchical structure:

Table L.E.26.1 - pizza service

"Price", "quantity" and "revenue" are the key figures in this example. Each customer has an additional attribute "C_cu_add", the customer's address.

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!

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