The quality of agricultural price data has been a growing concern of producers, researchers, and government officials in recent years. The major work done on improving agricultural price data has, of course, taken place within the United States Department of Agriculture. These efforts have not only led to the identification of key problems and issues in price reporting but have also resulted in a deeper investigation into our data and information systems. While an information system theory as such has not been developed, significant contributions have been made in terms of insights gained into the issues, the definitions and the epistemological nature of data systems and information systems. This study will be done in the context of these insights into the nature of data and information systems.
