b) A storage area (St-#) consists of several storage locations (SL-#). A storage location can belong to only one storage area.

c) Many parts can be stored in different storage locations, the "Inventory Level".

d) "Order Headers" are combinations of customers (Cust-#) and time (Date) and represent the order.

e) The relationship between order header and part is defined as order line item. Several parts can belong to an order in a given time (Date).
