Design Patterns

Hi all,

We had discussed some design patterns in the tech session, i.e.
- Fundamental Patterns:
Encapsulation and Information Hiding
Inheritance / Subclasses
Polymorphism
Exceptions

- Creational Patterns:
Lazy initialisation
Singleton
Multiton

- Structural Patterns:
Facade
Flyweight
Proxy

- Behavioral Patterns:
Iterator
Null Objects
Specification(pattern)

- Concurrency Patterns:
Event-based Asynchronous
Thread pool
Lock

We also managed to discuss something related with architectural patterns:
- MVC and Presentation-Abstraction Control
- Multitier Architecture
- Naked Objects

We knew that the application of design patterns is different from the coding itself, but it is a concept during the development of certain system.
