  Single Responsibility Principle (SRP) => object should only have single responsiblity
  Open/Closed Principle (OCP) => should be open for extension , but closed for modification
  Liskov Substitution Principle (LSP) => design by contract
  Interface Segregation Principle (ISP) => many client interfaces are better than one general purpose interface
  Dependency Injection Principle (DIP) => one should 'depend upon abstractions, not depend upon concretions'
