According to the structured development tradition, information systems are generally described in terms of three major components: data flows, data structures and processes. Data flows are the subject of the chapters on DFDs (chapter 17) and data dictionaries (chapter 19). Data structures have been discussed using the techniques of normalisation (chapter 15) and E-R diagramming (chapter 16). The third component, processes, are the subject of the current chapter.
