1 Context Facade is a structural design pattern that provides a simplified (but limited) interface to a complex system of classes, library or framework. A facade can improve the readability and usability of a software library by masking interaction with more complex components behind a single (and often simplified) API or provide a context-specific interface to more generic functionality (complete with context-specific input validation). Also, it serve as a launching point for a broader refactor of monolithic or tightlycoupled systems in favor of more loosely-coupled code.

2 Problem description Suppose You like to control your home appliances with the help of a Smart Remote. The Home Appliances will act as receiver here. Smart Remote will act as an invoker. To make it little user-friendly, I am trying here to provide command as statement like turn on bedroomlight or bedroomlight switch off. Woow. Thats interesting :) You want to control your smart devices such as a fan, TV, music system, light, coffee machine, electric grill, refrigerator, microwave, light in your home, some of which are in the living room and some in the kitchen. But some devices can be in both rooms, for example the light. The functions used in the controlled light in the living room may be different in the kitchen or additional features may be required. You should consider functions such as volume or power reduction and increase, which are available in many devices. For example; changing the channel on the TV, reducing the volume or turning it to mute, turning on the grill of the microwave, setting the timer to adjust the temperature while cooking, changing the modes of the refrigerator, etc. Yaay, you are having a party at home with friends !!!
