* Single Responsibility : Sınıflarımızın iyi tanımlanmış tek bir sorumluluğu olmalı.
* Open/Closed : Sınıflarımız değişikliğe kapalı ancak yeni davranışların eklenmesine açık olmalı.
* Liskov Substitution(yerine koyma) : Kodumuzda herhangi bir değişiklik yapmaya gerek kalmadan türetilmiş sınıfları (sub class) türedikleri ata sınıfın (base class) yerine kullanabilmeliyiz.
* Interface Segregation : Genel kullanım amaçlı tek bir kontrat yerine daha özelleşmiş birden çok kontrat oluşturmayı tercih etmeliyiz.
* Dependency Inversion : Katmanlı mimarilerde üst seviye modüller alt seviyedeki modüllere doğruda bağımlı olmamalıdır.
