## Executive Summary
This query retrieves monthly revenue trends for the last 12 months. Performance risk: **HIGH** — full table scan on orders (12M rows). Estimated execution time: 4.2s on current data volume.
 
## Data Flow Analysis
```
orders (12M rows)
→ FILTER: created_at >= DATEADD(month, -12, GETDATE())
→ GROUP BY: YEAR(created_at), MONTH(created_at)
→ AGGREGATE: SUM(amount), COUNT(*), AVG(amount)
→ ORDER BY: year DESC, month DESC
```
 
## Performance Findings
| Issue | Severity | Impact | Recommendation |
|-------|----------|--------|----------------|
| No index on created_at | 🔴 Critical | Full table scan | CREATE INDEX ix_orders_created ON orders(created_at) |
| YEAR()/MONTH() on column | 🟡 Medium | Index unusable | Use range predicate instead |
| No TOP/FETCH FIRST | 🟢 Low | Unbounded result | Add FETCH FIRST 12 ROWS ONLY |
 
## Statistical Insights
- **Peak month:** March 2024 — €142,300 (+23% vs prior month)
- **Lowest month:** August 2024 — €89,100 (seasonal dip)
