## Migration Commands

### Using Alembic (Recommended)

```bash
cd backend

# Generate migration
alembic revision --autogenerate -m "Add marketplace and sniper alert tables"

# Apply migration
alembic upgrade head
```

### Manual SQL (Alternative)

Run the SQL statements above in order on your PostgreSQL database.

---

## Verification

After running migrations, verify tables exist:

```sql
SELECT table_name 
FROM information_schema.tables 
WHERE table_schema = 'public' 
AND table_name IN (
    'domain_listings',
    'listing_inquiries', 
    'listing_views',
    'sniper_alerts',
    'sniper_alert_matches'
);
```

- **analysis_3.md** - "Micro-Marktplatz" (For Sale Landing Pages)
- **analysis_3.md** - "Sniper Alerts" (Strategie 4: Alerts nach Maß)
- **concept.md** - "For Sale Pages" marketplace feature
