Structural Design Patterns in Modern C++ - Introduction to the Facade Pattern

The video tutorial explains the Facade design pattern, which acts as a layer around a system to simplify complex interfaces and decouple clients from system components. It highlights the advantages of using a Facade, such as providing a unified interface and making subsystems easier to use. The tutorial covers different implementation methods, including functions, classes, and Singleton patterns. It also distinguishes between transparent and opaque facades, which either allow or restrict direct access to underlying classes. Finally, it outlines the responsibilities of a Facade in handling client requests and performing additional processing.
