In “Data: The Prerequisite for Everything Analytical”., Davenport, et al., present seven key components (structure, uniqueness, integration, quality, access, privacy and governance) of data management for analytics as employed by the most sophisticated companies. They say “You can’t be analytical without data, and you can’t be really good at analytics without really good data”. Discuss one level of uniqueness, why uniqueness is important to an organization, and an example (from your own industry or others) of what kind of analytics is performed over such data Discuss why data quality is important to analytics, describe one approach that you as a data scientist would use to find data quality issues, and also how you would go about fixing those issues
