→Facade Pattern
== Facade Pattern ==
The Facade Pattern is used to consolidate numerous complicated objects and function calls in a single interface. It does not necessarily encapsulate the objects behind the facade, as it commonly allows the client to work directly with the object.
A facade is like a house. Someone walking by the house sees the exterior and knows the functionality contained within the house (shelter, kitchen, bathroom, bedrooms, etc), but does not know how they are set up or laid out (ie implemented). The person walking by can approach the house and interact with its functionality through the front door, which is the single point of access to that which is contained within the house (ie sub-system).
