Facade Design Pattern

Provide a unified interface to a set of interfaces in a subsystem. Facade defines a higher-level interface that makes the subsystem easier to use.

👍 Advantages

Minimizes complexity of sub-systems
Aids principle of loose coupling
Software becomes more flexible and easily expandable

👎 Disadvantages

Complex implementation (especially with existing code)
Approach is coupled to an additional level of indirection
High degree of dependence at facade interface
