SQL Analysis Plan

Core Workflow

1. Identify business question, grain, tables, fields, filters, time window, segments, and expected output.
2. Outline query logic with joins, CTEs, aggregations, window functions, and validation checks.
3. Define data quality checks for duplicates, missing values, timezone, late events, and source mismatches.
4. Include expected result shape and interpretation caveats.
5. Keep database access read-only unless the user explicitly approves otherwise.
6. Flag missing schema information before writing final SQL.
