Creating reports in SQL to find missing data during the normalization process is crucial for maintaining data integrity.
Common SQL reporting patterns like NOT EXISTS, IS NULL, CASE, and boolean-style flags can help detect and quantify data anomalies.
Examples include identifying orphaned records, detecting null values in critical fields, and flagging inconsistent data types or logic.
By automating the reporting pipeline, outputting results to dashboards, and following best practices, SQL-based data integrity reports can be made more actionable and accessible.
