You are to draw a star schema diagram for this data which comes from a prototype of the data warehouse. There should be four $(4)$ dimension tables in your diagram $($named the same as the headings in the Excel file$)$ and one $(1)$ fact table $($named something that makes sense $[$call it FACT$]).$ Remember, the fact table should include in it the PKs from each of the $4$ dimensions $($these are to be both PKs and FKs in the fact table$).$ It will also include the value attribute in it from the

Excel file, which is a derived or calculated field. The dimensions should each have their own PK and three $(3)$ additional attributes $($minimum$)$ that make sense to add $($i$.$e$.,$ the item name, item description, and item cost in the ITEM dimension for example$).$
