Data Dictionary

Document both views. State the grain in one sentence, identify the keys, and list the measures (the columns you can aggregate). Replace every TODO.

vw_fact_trips

  • Grain: TODO (one sentence, e.g. "One row per ...")
  • Primary key: TODO
  • Foreign keys: TODO
  • Measures: TODO (columns you would SUM or AVG)

vw_dim_zones

  • Grain: TODO
  • Primary key: TODO
  • Foreign keys: TODO (or "none")
  • Measures: TODO (or "none, descriptive attributes only")
