Using a natural key ( when one can be identified ) also simplifies data quality: It ensures that there can only be one row for a key ; this " one version of the truth " can be verified, because the natural key is based on a real-world observation.

A key point is that, on large scales, our universe appears to be constructed along very simple lines: All current observations suggest that, on average, the structure of the cosmos should be approximately the same, regardless of an observer's location or direction of observation: the universe is approximately homogeneous and isotropic.
