SOLID principles Single Responsibility Principle: A class or method needs to be modified for one and only one reason. Open/Close principle: A class must be open for extension and closed for modification Liskov's substitution principle: A class and its subclasses must be exchangeable.  Interface segregation principle: A class must not be made to implement methods it does not need. Dependency inversion principle: High level module must not depend on low level modules. Both must depend on abstraction. Abstraction should not depend on details. Details should depend on abstraction. DRY - Do not repeat yourself. KISS - Keep it simple stupid.
