Project Structure

This project uses a standard Spring Boot layered architecture.

DTO Classes Explanation

This project follows the DTO (Data Transfer Object) pattern to separate the data used in forms from the data displayed in views:

• CreateCarDTO – used when creating a new car via the form. Contains validation for required fields.
• UpdateCarDTO – used when updating an existing car via the form. Also includes validation rules.
• CarDTO – used to display car data in lists and detail views.

Using these DTO classes ensures that the Entity (CarEntity) is not directly exposed to the web layer, making the application safer and easier to maintain.
