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.
Wisdom in DIKW - (answers)Provides a social setting to knowledge; an
understanding of the "why". Can only come by having both knowledge and
experience.
Information Systems - (answers)A collection of data and information used to
