3. Create a view named order_item_products that returns columns from the Orders, Order_Items, and Products tables. This view should return these columns from the Orders table: order_id, order_date, tax_amount, and ship_date. This view should return these columns from the Order_Items table: item_price, discount_amount, final_price (the discount amount subtracted from the item price), quantity, and item_total (the calculated total for the item). This view should return the product_name column from the Products table. 4. Create a view named product_summary that uses the view you created in exercise 4. This view should return summary information about each product. Each row should include product_name, order_count (the number of times the product has been ordered) and order_total (the total sales for the product). 5. Write a SELECT statement that uses the view that you created in exercise 5 to get total sales for the five best selling products.
