What are some use cases for the mediator pattern in software design?

The mediator pattern is useful in scenarios where you want to reduce the complexity of communication between multiple objects. For example, in a chat application, the mediator can manage the messages between users.

Can you give me another example?

Sure! In a flight booking system, the mediator can handle interactions between different components like the user interface, the booking service, and the payment service, ensuring they communicate effectively without being tightly coupled.

What are the benefits of using the mediator pattern?

The main benefits include reduced dependencies between components, easier maintenance, and improved scalability of the system.

Are there any drawbacks to using this pattern?

Yes, one drawback is that it can introduce a single point of failure if the mediator itself has issues. Additionally, it may lead to a more complex mediator if not designed carefully.
