   That depends on what's in these tables.   
      
   If a given product can be associated with one given invetory at a time, the   
   InventoryId would be a foreign-key column in the Products table.   
      
   On the other hand, if the Inventory table contains something like the stock   
   of all products at all warehouses, the ProductId column would be a foreign-   
   key column in Inventory.
