Sales order 1NF WGU C170 Data Management - Applications Performance Assessment. EXPLANATION: I am going to call this table the "Order Table" I also need to make sure that this table contains a primary Key, in this particular table I am going to make the “OrderID” and “DonutID” the Primary Key (composite key), the reason I chose to use OrderID and DonutID as the primary key is because Order ID or DonutID by themselves do not guarantee Uniqueness but when combined uniqueness ...
