Dear Experts,
I would to know your valuable suggestions for requirement as mentioned below.
Most of the products delivered using packing box and few without box (use wrapping).
Each packing box suites for few products but each product will have only one packing box only.
Which sample suites best?
/* Sample 1
Packing Box:
   PackingBoxID (PK), BoxNumber (UQ), Length, Width, Height, Gross Weight
Product:
   ProductID (PK), ProductNumber (UQ), ...,PackingBoxID
*/
/* Sample 2
Packing Box:
   PackingBoxID (PK), BoxNumber (UQ), Length, Width, Height, Gross Weight
Product:
   ProductID (PK), ProductNumber (UQ), ...,
ProductPackingBox:
   ProductID, PackingBoxID
*/
Thank you.

Correct me if I'm wrong, but a given product will have multiple instances. Let's assume a can of oil. We can define all the properties about that can of oil, but, we don't have one can that we put into a shipping box. We have lots of cans that go into lots of shipping boxes. Based on that, you probably need some sort of Inventory table (or maybe just a counter on the Product table, disagreement can be had here) that defines what you're shipping. Then, the second design, multiple products to multiple shipping boxes, makes more sense.

Thank you.

If a particular product is always delivered in the same box type, one product per box, then PackingBoxID is an attribute of the Products table.
