Driver and Vehicle Licensing Department

DVLD Desktop Application is a C# WinForms management system designed to handle driver and vehicle licensing services. The project follows a three-layer architecture: Presentation Layer, Business Logic Layer, and Data Access Layer. This structure improves maintainability, separates responsibilities, and makes the system easier to scale and update. The system provides modules for managing people, drivers, users, applications, licenses, test types, and application types. It supports key licensing services such as issuing local and international driving licenses, renewing licenses, replacing lost or damaged licenses, releasing detained licenses, and retaking driving tests. The backend database is built with SQL Server, while the Data Access Layer handles database communication and CRUD operations. The Business Logic Layer contains validation rules and core application logic, and the Presentation Layer provides a user-friendly WinForms interface.
