Insyt data dictionary

Different values reports observed distinct values in this dataset snapshot. It does not prove that a column is a unique key in future data, or that a combination of fields will be unique.

Never empty means no nulls were observed in the snapshot. Empty strings, invalid codes and future missing records may still need checks.

Before joining: state each table's grain, check key uniqueness, choose an appropriate join and reconcile counts and measures. For a worked order-line join, open the data catalogue.
