The Facade Design Pattern is a structural design pattern that provides a simplified interface to a complex subsystem. It is part of the Gang of Four design patterns and is commonly used in object-oriented programming12. The pattern hides the complexities of the underlying system and provides a unified interface that clients can use to interact with the system.
Key Principles
The primary goal of the Facade pattern is to minimize the communication and dependencies between subsystems. By introducing a Facade object, it provides a single simplified interface to the more general facilities of a subsystem1. This helps in reducing the complexity and making the subsystem easier to use.
Example
Consider a hotel with multiple restaurants (Veg, Non-Veg, and Both). As a client, you want access to different menus but do not know the details of each restaurant. The hotel keeper acts as a Facade, providing you with the required menus without exposing the complexities of the underlying system1.
