DFD Example

DFD is expressed using an intermediate language similar to the C language.

The images below are from the lecture notes passed out by Prof. Shubashish Dasgupta in September 2005. Please refer to http://www.marcoullis.com/KNOWLEDGE/SYSTEMS/marcoullisp_systems_process_modelling.html

The DFD diagrams are produced in Demarco and Yourdon standard, different from Gane and Sarson standard.
