In order to analyse data monthly about the tickets sold per draw in each location (including online) with different types (based on the different number of lines) over a period of three years, a data warehouse is being planned. It is assumed that each line generates $1.5 of sale and there is a minimum of 4 lines per ticket. Based on the number of lines a ticket has, a ticket is classifies into three types: small (4 or 5 lines), medium (6-9 lines) or large (10 or more lines). The management of the Lotto Game is interested to know which location (and sub-location) sells which type of ticket in a draw, and whether the ticket wins the jackpot.
