Pipes and Filters Design

The idea of pipes and filters is that you have a set of filters. A filter receives data at the left side, does something with it and pumps it out on the right side. And e, if you want to build e a complex for example, image transformation or filtering, than you can build a chain of filters which are connected by pipes. Another very well known pipes and fis filters application is the eunuch shell - where the term pipe was literally used to connect various command line applications.
