Tight coupling between a set of interacting objects should be avoided. The Mediator is a behavioral pattern (like the Observer or the Visitor pattern) because it can change the program’s running behavior. Mediator promotes loose coupling by keeping objects from referring to each other explicitly, and it lets you vary their interaction independently” (Design Patterns: Elements of Reusable Object-Oriented Software, 2013, p. 273).
