DATA & INFORMATION & KWONLEDGE
• KNOWLEDGE– Information from the human mind (includes
reflection, synthesis, context ), which guide human behavior in correct way.
– Information synthesized and contextualized to provide value.
• Hard to structure • Difficult to capture on machining • Hard to transfer
