Chain of Responsibility(225) Avoid coupling the sender of a request to its receiver by giving more than one object a chance to handle the request. Chain the receiving objects, and pass the request along the chain until an object handles it.

Command(245) Encapsulate a request or operation as an object, thereby letting you parameterize clients with different operations, queue or log requests, and support undoable operations.
