Assume that the transaction summary report for the RMO order-entry subsystem (see in Figure) contains a listing of every order that was created during a date range entered by the user. The report title page contains the report name, the date range, and the date and time the report was prepared. For each order, the report lists the order number, order date, order total, and form of payment. Within each order, the report lists all order items and returns, including item number, quantity ordered (or returned), and price. Report totals include the sum of all order totals, average order total, average item price, and average return price. Write a data flow definition entry for the report, and write a process specification for the process that produces thereport.
