Capture as much data as possible in Level 2 (structured). Storage has become so affordable and available that the limitations of a decade ago no longer apply. Since we don’t know what questions we may have in the future, it is better to err on the side of abundance. If we can capture the data, we should.
Make sure the data is correct that it accurately represents the most current reality.
Have an efficient reporting engine that provides timely answers to relevant questions.
