# ISOSettings Module Documentation

## 1. Purpose

The ISOSettings module manages configuration related to ISO (International Organization for Standardization) code support within the DataPRO system. It provides a model layer for persisting and retrieving ISO-related settings—such as display modes, validation rules, and support levels—via a database-backed settings store. The module also orchestrates side effects when critical validation settings change, triggering re-evaluation of test completeness across the system.

| `ShowISOCodes` | Key for ISO code visibility |
| `ShowUserCodes` | Key for user code visibility |
| `UseUserCodes` | Key for user code usage |
| `IsoSupportLevel` | Key for ISO support level |
| `UniqueISOCodesRequired` | Key for unique ISO code requirement |
| `ShowISOStringBuilder` | Key for ISO string builder visibility |

### Class: `ISOSettingsModel`
**Namespace:** `ISOSettings.Model`  
**Implements:** `IISOSettingsModel`

#### Constructor
```csharp
public ISOSettingsModel(IEventAggregator eventAggregator)
```
Initializes the model with an event aggregator for publishing notifications.

#### Methods

```csharp
public IISOSettingsData LoadData()
```
Returns a new `ISOSettingsData` instance populated with current settings values.

```csharp
public void SaveData(IISOSettingsData data)
```
Persists settings from the provided `ISOSettingsData` instance. If `UniqueISOCodesRequired` or `ValidateTestObjectAndPosition` values change, triggers `MarkAllTestsDirty()`. Sets `IsSaved` to `true` on success; publishes a `RaiseNotification` event on exception.

```csharp
public void OnPropertyChanged(string propertyName)
```
**Note:** Empty implementation—does not raise `PropertyChanged` event.
