title: How to reduce order form to 3NF?
body: <p>I'm practicing normalization for class and had this as an example and I'm wondering how to reduce this to 1NF first hand?</p>

  <p>The tables look alright to me, I don't see any repeating information, and the Product ID I think is a good Primary Key. For the first table above, would deleting the Due Date be a step? Also, for the Subtotal columns at the bottom, is that included in the data structure as well? </p>
  
  <p>Thanks</p>
