Save the data normalized.
the bridge table Order_product has a m:n relation ship.
you can extend the schema, by adding a city table country table and so on so that you save only integers instead of city names
Customer product order Order_Product
c_id p_id o_id o_id
c_name p_name o_date p_id
c_adress c_id qty
c_city rate
Joining all tables by their foreign keys you can easily get all nformation yu want
