All businesses use data collection systems, they just don’t call them that. They call them accounting programs, e-mail programs, bulk mailing programs and telephone systems. If this list seems a bit strange, think about it. All of these collect data, store it and organize it. Before businesses used computers, they still had in place, at lease one business data collection system; double entry accounting.
They usually had more because they had filing cabinets, address and telephone books and a calendar. While the computer has automated many of these systems, it is still a business data collection system.
