Exercise No. 9: Sales Process (log)

We will now build a logical model for the "sales process" case. We have four dimensions with the following hierarchical structure:

Table L.E.3.1 - sales process

"Revenue" and "Number of purchases" 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
