Design patterns

• Some people choose to implement interfaces in ruby like this:

    class InterfaceModel
      def something
        raise NotImplementedError, "Implement this method in a child class"
      end
    end

• I chose not to implement them and just create classes like they were supposed to implement all the methods.

• Abstract Factory
• Factory Method
• Builder
