Design Patterns used
7
• MVC (Model-View-Controller)
• Unit of Work (Repository)
• Service Locator (Inversion of Control container)
• Composition Root (Modules Dependency Inversion)
• Dependency Injection (Class Constructor Injection)
• Factory pattern
• Iterator pattern
• Observer pattern

8.
Design Principles used
(S.O.L.I.D.)
8
• Single Responsibility principle
(class should have only one responsibility)
• Open-Closed principle
(class should be opened for extension and closed to modification)
• Liskov Substitution principle
(subtypes should be substitutable for its base types)
• Interface Segregation principle
(interfaces should not be “fat”)
• Dependency Inversion principle
(depend upon abstraction, not upon concretion)
