Unformatted Sample Text from the Research Paper:
white wallboard the information pertaining to number of seats sold, prices for hotels and other pertinent information is kept. All of the reports are created in WORD documents.  These include the billing, flight manifests, and seat assignments.

Different data will need to go to different
