Designing

1. SOLID Principles

   • Single Responsibility Principle
     • A class should have only 1 reason to change. A class should also only have a single responsibility
   • Open/Closed Principle
     • A class should be open for extension, but closed for modification. Should allow to extend functionalities, but not allow modifications inside the class
   • Liskov Substitution Principle
     • A derived class should be able to substitute for the parent class
   • Interface Segregation Principle
     • Large interfaces should be separated into smaller ones, so that you don't have to implement methods you don't need to use.
   • Dependency Inversion Principle
     • Classes should have to rely on interfaces to depend on some other class?
