# Documentation: Database View Components

## 1. Purpose

This module provides WPF view components for database-related UI operations within the DatabaseServices namespace. It contains three code-behind classes—`DatabaseStatusBarView`, `DatabaseCopyView`, and `DatabaseSwitchView`—that serve as the visual layer for displaying database status, copying databases, and switching between local/remote database connections respectively. These views implement interfaces from `DTS.Common.Interface.Database` and delegate business logic to associated ViewModels via WPF data binding.

---

## 2. Public Interface

### `DatabaseStatusBarView`
**Namespace:** `DatabaseServices`  
**Implements:** `IDatabaseStatusBarView`

```csharp
public DatabaseStatusBarView()
```
Default constructor. Calls `InitializeComponent()` to load the associated XAML layout. No additional public members are exposed beyond the interface implementation.

---

### `DatabaseCopyView`
**Namespace:** `DatabaseServices`  
**Implements:** `IDatabaseCopyView`

```csharp
public DatabaseCopyView()
```
Default constructor. Calls `InitializeComponent()` to load the associated XAML layout.

```csharp
private void Copy_Click(object sender, RoutedEventArgs e)
```
Event handler for the copy button click. Casts `sender` to `Control`, retrieves the `DataContext` as `IDatabaseCopyViewModel`, and invokes `vm.CopyDatabase()`.

---

### `DatabaseSwitchView`
**Namespace:** `DatabaseServices`  
**Implements:** `IDatabaseSwitchView`

```csharp
public DatabaseSwitchView()
```
Default constructor. Calls `InitializeComponent()` to load the associated XAML layout.

```csharp
private void SwitchToLocal_Click(object sender, RoutedEventArgs e)
```
Event handler for switching to local database. Casts `sender` to `Control`, retrieves the `DataContext` as `IDatabaseSwitchViewModel`, and invokes `vm.SwitchLocal()`.

```csharp
private void SwitchToRemote_Click(object sender, RoutedEventArgs e)
```
Event handler for switching to remote database. Casts `sender` to `Control`, retrieves the `DataContext` as `IDatabaseSwitchViewModel`, and invokes `vm.SwitchRemote()`.

---

## 3. Invariants

- **DataContext Contract:** `DatabaseCopyView` requires its `DataContext` to be an instance of `IDatabaseCopyViewModel`. `DatabaseSwitchView` requires its `DataContext` to be an instance of `IDatabaseSwitchViewModel`. Event handlers will fail with invalid
