Design a multi$-$dimensional model $($i$.$e$.,$ star$/$snowflake schema$)$ for the retail product returns process

$($see the data warehouse business matrix in that article$).$ Each table$/$entity$,$ including the dimensions

and the fact table, should have at least three attributes including a primary key $($and a foreign key, if

needed$).$ You can simply use Shapes in MS Word to draw the model. However, if you decide to use any

other tools $($e$.$g$.,$ Lucidchart or Visio$),$ just provide an image or screenshot of the model here. For the

connections $($relationships$)$ between entities in the model you can use simple lines or arrows; you do

not have to add other details to the connections
