The video tutorial explains the process of creating a data model for a course type in Web API projects. It begins with an introduction to data models, which are classes that correspond to database tables. The tutorial then guides viewers through creating a course class with properties like course ID, name, duration, and type. It addresses handling compilation errors related to nullable features in .NET 6. Finally, the course class is finalized, and the tutorial sets the stage for using this data model in future implementations.
