Define: Facade pattern

A facade is an object that provides a simplified interface to a larger body of code, such as a class library. A facade can:

• * make a software library easier to use and understand, since the facade has convenient methods for common tasks;
• * make code that uses the library more readable, for the same reason;
• * reduce dependencies of outside code on the inner workings of a library, since most code uses the facade, thus allowing more flexibility in developing the system;
• * wrap a poorly designed collection of APIs with a single well-designed API (As per task needs).
