Awesome discussion during Design pattern training of Mumbai branch.

In the last design pattern training in Mumbai Andheri we had one question from a smart participant. What is difference between façade and mediator. Façade and mediator look very similar but they are not.

Façade gives a easy way to access your subsystems while mediator takes care of object collaborations. So both of them tend to look like a wrapper on subsystems. But there are two big differences which make them stand apart :-

Façade does not add any functionality while mediators adds functionalities of interaction.

Façade does not communicate back while mediator communicates back.
