    price:        {type: integer, required: true}

    id:           ~
    order_id:     {type: integer, required: true, foreignTable: order, foreignReference: id, onDelete: cascade, onUpdate: cascade}
    product_id:   {type: integer, required: true, foreignTable: product, foreignReference: id, onDelete: cascade, onUpdate: cascade}

  order:
    id:           ~
    name:         {type: varchar(255), required: true}

  }
}
