S.O.L.I.D Principles

1. Single Responsibility Principle
2. Open-Closed Principle
3. Liskov Substitution Principle
4. Interface Segregation Principle
5. Dependency Inversion Principle

Design Patterns

Are solution templates for a wide range of recurring problems in software engineering. They can be classified into 3 types:

1. Creational Patterns: They abstract the instantiation process. Thus a system that uses this pattern doesn’t need to know how it’s objects are created.
   • Abstract Factory Pattern
   • Builder Pattern
   • Singleton Pattern
2. Behavioural Patterns: Are concerned with algorithms and assignment of responsibilities between objects. This is done by establishing efficient communication between them.
   • Observer Pattern
   • Command Pattern
   • Strategy Pattern
3. Structural Patterns: They are concerned with how classes and objects are composed to form larger structures.
