Projection: Orders Average, OrderItems AverageInstructions: Columns to display are determined by whether your output is horizontal (two columns) or vertical (one column holding both averages on separate lines with a literal string telling what each average is). There are two possible averages on this question. There are a certain number of orders in the ORDERS table, but not all of these orders are in the ORDERITEMS table. Write one query that produces both averages. To get this answer, you need to add up all the order values and divide by the number of orders. The number of orders in the ORDERS table is different from the number of orders in the ORDERITEMS table.Do not use AVG(). 8. Who is our most profitable salesperson? Projection: SALESPERSONS.EmpID, SALESPERSONS.Ename, (SUM(ORDERITEMS.Qty*INVENTORY.Price) SALESPERSONS.Salary) Instructions: A salespersons profit (or loss) is the difference between what the person sold and what the person earns: ((SUM(ORDERITEMS.Qty*INVENTORY.Price) SALESPERSONS.Salary)). If the value is positive then there is a profit, otherwise there is a loss. The most profitable salesperson, therefore, is the person with the greatest profit or smallest loss. Display the most profitable salesperson (there can be more than one). 9. Who is our second-most profitable salesperson?Projection: SALESPERSONS.EmpID, SALESPERSONS.Ename, (SUM(ORDERITEMS.Qty*INVENTORY.Price) SALESPERSONS.Salary)Instructions: A salespersons profit (or loss) is the difference between what the person sold and what the person earns:((SUM(ORDERITEMS.Qty*INVENTORY.Price) SALESPERSONS.Salary)). If the value is positive then there is a profit, otherwise there is a loss. The most profitable salesperson, therefore, is the person with the greatest profit or smallest loss. The second-most profitable salesperson is the person with the next greatest profit or next smallest loss. Display the second-mostprofitable salesperson (there can be more than one). Do not hard-code the results of a previous query that simply creates a data-dependent query. What are the discounts for each line item on orders of five or more units?Projection: Orderid, Partid, Description, Qty, Unit Price, Original Price, Quantity Deduction, and Final PriceInstructions: We have decided to give quantity discounts to encourage more sales. If an order contains five or more units of a given product we will give a two percent discount for that line item.

Display only those line items subject to the discount in ascending order by the OrderID and PartID. Use the CASE statement.
