The Facade pattern is one of the Gang of Four's structural design patterns.
The facade pattern is a software engineering design pattern commonly used with Object-oriented programming. The name is by analogy to an architectural facade.
It is one of the Gang of Four's structural design-patterns, first published in Gamma et al.'s book "Design Patterns: Elements of Reusable Object-Oriented Software".
From Wikipedia: The Facade pattern provides a unified interface to a set of interfaces in a subsystem. It defines a higher-level interface that makes the subsystem easier to use.
