&amp;#039;&amp;#039;&amp;#039;Chain of Responsibility(225)&amp;#039;&amp;#039;&amp;#039; 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.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Command(245)&amp;#039;&amp;#039;&amp;#039; Encapsulate a request or operation as an object, thereby letting you parameterize clients with different operations, queue or log requests, and support undoable operations.&lt;br /&gt;
