## 10. Data Maintenance & Optimization
### Performance Optimization
1. **Regular Index Analysis**: Monitor slow queries
2. **Table Optimization**: `OPTIMIZE TABLE` for tables > 100MB
3. **Partition Strategy**: Consider date-based partitioning for scan tables
4. **Archiving**: Archive quality scans older than 2 years
### Backup Strategy
- **Daily automated backups** → `/srv/quality_app/backups/`
- **Retention**: 30 days (configurable)
- **Backup types**: Full + data-only incremental backups
### Data Cleanup Recommendations
```
scan1_orders, scanfg_orders
└─→ Archive data older than 2 years
permission_audit_log
└─→ Archive quarterly
dm_daily_summary
└─→ Keep all historical data
```
---
## 11. Production Phases Tracking
The system tracks three phases of production:
### Phase T1: Quilting Preparation
- Table: `scan1_orders`
- Fields in `dm_production_orders`:
- `phase_t1_prepared` (status)
- `t1_operator_name` (who performed)
- `t1_registration_date` (when scanned)
- `end_of_quilting` (completion date)
### Phase T2: Cutting
- Fields in `dm_production_orders`:
- `phase_t2_cut` (status)
- `t2_operator_name`
- `t2_registration_date`
### Phase T3: Sewing/Assembly
- Fields in `dm_production_orders`:
- `phase_t3_sewing` (status)
- `t3_operator_name`
- `t3_registration_date`
- `end_of_sewing` (completion date)
### Final Goods (FG) Quality
- Table: `scanfg_orders`
- After all phases complete
