The nature of the pure pipe-and-filter systems allows an architect to construct complex data flow system from simpler components. This method allows an architect to understand, in detail, the properties of simpler components. Additionally, an architect can start from a simple system with just a few components, and then build up a more complex system. We can reason about the EXAMPLE in the following manner. It is given that when the input stream X enters filter F, the OUTPUT stream will be F(X). The output stream F(X) sequentially becomes an input stream to filter G, and the output stream of filter G is G(F(X)). In a similar manner the input stream G(F(X)) enters filter H and the FINAL output stream of the system is H(G(F(X))). The following computation LEADS to the final result by using the results of previous computation.
