I just started working on one of the application, bascially its some maintanence work. I see from the application that Facade pattern has been utilized as I see Class Library projects named as Business Facade, Data Facade.
Though I am not redesigning this, but just wanted to know what this pattern is, a simple explanation, use, real world example should be good enough. The application is basically a banking app. I know its diff but if anyone can give me some hints/points as in why the designer chose this pattern (banking app).
