# Documentation: DatabaseImport Application Module

## 1. Purpose

This module provides UI state management utilities for a WPF-based database import application. It consists of two components: `WaitCursor`, a disposable utility class for temporarily displaying a wait cursor with automatic restoration, and `App`, the main application class that manages application-wide busy states, provides lazy-initialized access to an `ISO13499FileDb` instance, and handles thread-safe UI manipulation through dispatcher-aware methods.
