Behavioral Design Patterns in C++ - Introduction-Mediator

The video tutorial explains the mediator design pattern, which facilitates interaction between objects by using a central mediator object. This pattern reduces coupling and simplifies system modification. A real-life example of an airport is used to illustrate the concept. The tutorial covers the intent of the pattern, the role of colleagues and concrete mediators, and different implementation strategies, including the use of command and observer patterns.

What is the significance of reducing interconnections between objects in a system?

In what scenarios would you need to define an abstract mediator class?

How can the observer pattern be integrated with the mediator pattern?
