Create two classes to depict the use of this principle. This can be achieve via putting two contract methods in model classes where you provide their actual iogic. This method from the model may consume other objects to fulfill that responsibility.

Polymorphism

Implement at least one polymorphic method in your semester project.

Low Coupling

To support low coupling, Your model layer should interact with DAL layer via a controller as well. Create a DALController for all database related operations.

Protected Variation

In your semester project, where do you think this principle is applicable. Give example of two classes which may have been a single class but varing nature of some methods you split that into two classes.

Data Transfer Object

Create DTO objects wherever necessary. Your layers should pass the data in DTO's, direct value based parameters in method are strictly prohibited.
