Now we needs to assign for products the distributors that sell it.
We proceed to create ProductsDistributors table and relation it with Distributors table (already existent), to end define subtable for the products table.
Thanks to the subtables we can create a tree of tables considering them as an only entity. The data of each subtables will be stored in the database only when we save the root table.
