Get the right answers before making business decisions! Your data asset must be fueled by a single source of truth in order to provide the right answers to your questions. Requirements for a robust single source of truth may vary from one business organization to another but the underlying framework is universally the same.
The real business world consumes data as humans consume food for fuel and good health so we must understand how to leverage data sources that produce founts of trustworthy information. Each entity type lives in its own safe habitat, free from repeating data and other entities. For example, products, persons and locations each live in their own habitat. Many associations among these data sources may exist but the associations do not live in the same habitat as the sources themselves. Good data science practices provide the mechanisms for promoting excellent health of your data asset.
