This document discusses flow-based programming, an approach to programming invented in the 1970s where the flow of data between components is emphasized. It was successfully used in several domains including data analysis, banking software, and digital signal processing. New implementations of flow-based programming include NoFlo for Node.js and GoFlow, an open-source implementation in Go. More information on flow-based programming can be found on the listed websites.

Flow-based programming
●
Invented at IBM in the 70's
●
Successfully used in many areas:
– Data analysis and ETL (e.g. Pentaho Kettle, Pypes).
– Transactional business applications such as banking software
(originally FBP was made for it)
– Digital signal processing is flow-based
– Multimedia broadcasting (Kamaelia)
– Simulations (LabVIEW).
– Networking (AMQP is a similar approach)
