I am a bit confuse where I will implement the business Facade? In 3 tire distributed model, I want to add a facade in between presentation tire and business logic tier. They are running on a separate system. Now my question where should I implement the facade class in presentation tier or business tier.
If I am not wrong facade pattern represent a set of use case. There may multiple task can take place from a single call to the facade. Example credit card validation and payment. In this case it should be implemented on business tier.
Am I on the right path? Is there any example where we implement facade in first tier?
