This pattern is an improvement over the client/server architecture pattern. It is a recurring solution to a recurring problem. Domain Driven Design eases communication and improves flexibility. Sometimes, the reaction is not completely provided by a single Consumer that might forward the event to another component after it has filtered or transformed it. Also, it has a lower impact on the code than the architectural patterns since the design pattern is more concerned with a specific portion of code implementation such as initializing objects and communication between objects. The architectural style is a very specific solution to a particular software, which typically focuses on how to organize the code created for the software. It partitions the concerns of the application into layers. A Filter transforms the data it receives through Pipes with which it is connected. The Controller layer is in the middle and it is in charge to send data from the Model to the View and vice versa.
