1(a)
A manufacturing company has a huge sales network. To control the sales, it is divided into regions. Each region has multiple zones. Each zone has different cities. The object is to track sales figure at different granularity levels of region and also to count the number of products sold. Create data warehouse schema to take into consideration of above granularity levels for regions, sales person and quarterly, yearly and monthly sales.
