## 🧮 Calculation Methods

### Business Day Calculation
```php
if (date('H') < $Programsetting->reportsPlusHours) {
    $start = $startYesterday;
    $end = $endYesterday;
} else {
    $start = $startToday;
    $end = $endToday;
}
```

### Inventory Valuation
```php
switch ($Programsettingdata->Inventoryevaluation) {
    case "first":
        $priceColumnName = 'productBuyPrice';
        break;
    case "last":
        $priceColumnName = 'lastbuyprice';
        break;
    case "mean":
        $priceColumnName = 'meanbuyprice';
        break;
    // ... additional methods
}
$totalprice = (float) $myStoredetailEx->getM5zonPrice($priceColumnName);
```

## 🔒 Security & Performance

### Performance Considerations
- **Multiple Heavy Queries**: Dashboard executes 10+ analysis functions
- **Large Dataset Handling**: Date range filtering critical for performance  
- **Inventory Calculation**: Can be disabled via `showM5zon` setting
- **Concurrent Execution**: All analyses run in sequence, consider caching

### Required Indexes
- Date-based indexes on all transaction tables
- Customer/supplier debt indexes
- Product and inventory indexes
