Mediator Design Pattern
The Mediator Design Pattern is a behavioral design pattern that promotes loose coupling between objects by encapsulating their communication logic in a mediator object. This pattern is useful when a set of objects communicate with each other in complex ways, and the resulting dependencies become unmanageable. The mediator acts as a central point of control, facilitating communication between objects without them having to know about each other's existence. In this pattern, the mediator object is responsible for coordinating the interactions between the participating objects. It receives requests from one object and forwards them to the appropriate object(s) for processing. The mediator also receives notifications from objects and broadcasts them to the other objects. This approach helps to reduce the complexity of the interactions between objects, making the system easier to maintain and extend. One of the key benefits of the Mediator Design Pattern is that it promotes modularity and reusability. By encapsulating the communication logic in a mediator object, the participating objects can be easily replaced or modified without affecting the rest of the system. This makes it easier to add new features or change the behavior of the system without introducing new bugs or breaking existing functionality. Another benefit of this pattern is that it helps to reduce the number of dependencies between objects. In a complex system, objects may need to communicate with many other objects, leading to a complex web of dependencies. By using a mediator object, the number of direct dependencies between objects is reduced, making the system more modular and easier to understand. Overall, the Mediator Design Pattern is a powerful tool for managing complex interactions between objects. By encapsulating the communication logic in a mediator object, this pattern promotes loose coupling, modularity, and reusability, making it easier to maintain and extend complex systems.

Mediator Design Pattern
The Mediator Design Pattern is a software architecture design pattern which defines a centralized intermediary to control communication between two or more objects. This pattern helps to reduce direct dependencies between the involved classes and improves loose coupling. In this pattern an object, known as a mediator, helps facilitate communication and provides an interface that helps facilitate the flow of information between different objects. This pattern is especially useful in distributed enterprise applications where several components communicate with each other and need to optimize the communication between them.
