knowledge (and wisdom).
– Data: raw value elements or facts
–
Information: the result of collecting and organizing data that provides context and meaning
– Knowledge: the concept of understanding information that provides insight to information,
thus useful and actionable

of implications and indirect results beyond a target domain.
