Facade Architecture in ASP.Net:-

The facade is an interface that an application can use to get things done without worrying about the details. The facade decouples these layers so that they dont depend on each other, which makes each easier to develop, easier to use, and promotes code re-use. The Facade design pattern connects the code we write for applications, which do specific tasks, such as creating a report, and the low level implementation that handle the details, such as reading file, interacting with the network, and creating output.

I can use this design pattern to deal with a complex system that already exists, or one that I want to make from scratch.
