Dears,

I need unique and not hand written answer for this question:

Q) Design a star model that analyzes the sales of a fast food company. The principle is to measure sales through quantities sold and profits. For this, we are based on a function of the sales made per day, in a given restaurant, for a given food. The goal is to be able to analyze sales by day, by week, by month and by year. Restaurants can be grouped according to their city and country.
