Today's pattern is the Mediator pattern, used to handle complex communications between related objects, helping with decoupling of those objects.Mediator in the Real World An airport control tower is an excellent example of the mediator pattern. The tower looks after who can take off and land - all communications are done from the airplane to control tower, rather than having plane-to-plane communication. This idea of a central controller is one of the key aspects to the mediator pattern. The Mediator pattern is known as a behavioural pattern, as it's used to manage algorithms, relationships and responsibilities between objects.. The definition of Mediator as provided in the original Gang of Four book on Design Patterns states: Allows loose coupling by encapsulating the way disparate sets of objects interact and communicate with each other. Allows for the actions of each object set to vary independently of one another. Read more: DZone
