10.Dikw hierarchy - answer defines the transition of data to information
from knowledge to wisdom. (data information knowledge wisdom)
11.Data in dikw - answer the input directly received by the user (or
computer). It is generally not usable until it has been converted into a
relevant form.
12.Information in dikw - answer having been inferred from data; one or
more processes have been applied to the data to transform it into a more
useful form.

information placed into a context. Refined information such that the user
of the knowledge is able to call forth only relevant portions of information
when needed.
14.Wisdom in dikw - answer provides a social setting to knowledge; an
understanding of the "why". Can only come by having both knowledge and
experience.
