Hands-on .NET Minimal API for Web Developers - Step 11: Add DTO Models

The lecture explains how to enhance map operations using DTO models instead of data models. DTOs, or Data Transfer Objects, are used to transfer only necessary data between client and server, reducing payload size and hiding unnecessary details. The lecture covers the advantages of DTOs, such as data hiding, object flattening, and payload reduction. It also demonstrates how to implement DTOs in HTTP operations and define course DTOs in Web API projects. Additionally, it discusses enhancing course types with enums for better data representation.

Describe the process of defining a course DTO and its significance.

What is the purpose of using enums in the context of course types?
