The Facade design pattern introduces an intermediary object that provides a simplified interface to a complex low-level subsystem, decoupling client code from that subsystem's implementation details. This concept belongs to structural design patterns in object-oriented software design, and is commonly applied alongside the Model-View-Controller architectural pattern, in which responsibilities are separated into data, presentation (view), and business logic (controller). Together these patterns reduce coupling and improve cohesion by ensuring each component depends only on a minimal, stable interface rather than on the internal details of the systems it uses.
