3. Some authors have noted that “data” are the raw material for “information,” which is the raw material for “knowledge.” We think that the reverse direction is even more important. Knowledge created or developed by an individual or a group must eventually become structured data so others can apply that knowledge.

6. Many authors either consider properties of information rather than data or treat the two concepts as synonyms. It is instructive to compare our summary of data properties in Table 1 with those of information provided, for example, by:
H. Cleveland, “Information as a Resource,” The Futurist, volume 16, December 1982, pp. 34–39; and
C.F. Burk and F.W. Horton, InfoMap: A Complete Guide to Discovering Corporate Information Resources (Englewood Cliffs, New Jersey: Prentice-Hall, 1988).

8. Some authors use the term “assets” instead of “resources.” But “assets” is a narrower concept. According to the American Heritage Dictionary (1985), an asset is “anything owned that has exchange value” or “an entry on a balance sheet.” While almost all data clearly have value, most data are not for sale, and they do not appear on balance sheets, so they do not qualify as assets.

18. These observations do not contradict the observations regarding the difficulties of valuing data: to ascertain the qualitative fact of diminishing value, one does not have to know how to measure it precisely.

20. It could be argued that the “ability to store data” is a fundamental property of computers, not the other way around. This may be true. But the practical consequences to managers are the same.
