When a programming language is originally designed without any syntax to nest function calls, pipeline programming is a simple syntax change to add it. The programmer connects notional program modules into a flow structure, by analogy to a physical pipeline carrying reaction products through a chemical or other plant. The best-known example is the Unix pipe system, but many high level software design tools (such as the openDX display suite) provide a GUI pipeline programming tool that helps visualize data flow through a program. A data flow diagram (DFD) maps well to pipeline programming. However, exception handling can be one of the weaknesses.
