A ranged dimension is a dimension that is used to have a discrete view of a continuous measure. A good example of this is the analysis of amount sold per order. In AdventureWorks we have, for each line of an order, the amount and quantity sold. We would like to divide orders in three groups (HIGH, MEDIUM, LOW) based on the total of the order. This is a very frequent kind of analysis that is used to determine how much money customers are willing to spend in a single order and may be very useful to check whether there is any kind of relationship between the characteristics of a customer and his/her medium spending capability. |
