What is Facade package?
Standards: <> Package. A façade is a packaged subset of work products selected from the contents of a subsystem. Each façade provides public access to only those parts of the subsystem that have been chosen to be available for reuse. In other words, a model element that defines a subsystem interface.

Which is an example of a Facade class?
The facade class abstracts Packages 1, 2, and 3 from the rest of the application. The objects are using the Facade Pattern to access resources from the Packages. This is an abstract example of how a client (“you”) interacts with a facade (the “computer”) to a complex system (internal computer parts, like CPU and HardDrive).
How is the facade pattern used in programming?
The facade pattern (also spelled façade) is a software-design pattern commonly used in object-oriented programming. Analogous to a facade in architecture, a facade is an object that serves as a front-facing interface masking more complex underlying or structural code.
How does the client depend on the facade interface?
The Client depends only on the simple Facade interface and is independent of the complex subsystem. The sequence diagram shows the run-time interactions: The Client object works through a Facade object that delegates the request to the Class1, Class2, and Class3 instances that perform the request.
When to use an adapter or a facade?
A Facade is used when an easier or simpler interface to an underlying object is desired. Alternatively, an adapter can be used when the wrapper must respect a particular interface and must support polymorphic behavior. A decorator makes it possible to add or alter behavior of an interface at run-time. The facade pattern is typically used when
