1. What is data?

1.1. DIKW pyramid

The DIKW pyramid differentiates the terms data, information, knowledge, and wisdom in an interesting way: data is raw, information is contextualized data, knowledge is internalized information (which is then re-externalized through knowledge management ); wisdom is knowledge that is refined and applied with good judgement. I like to think about the amount and kind of human effort that goes into each conversion.
