Hi everyone,

in one of previous my posts, I illustrated the using of command design pattern (command query reponsibility separation with command processor) via here.in this post I will exemine this pattern as simpler.

Intent

– encapsulate a request in an object
– allows the parameterization of clients with different requests
– allows saving the requests in a queue
