Data Flow Sequences: A Revision of Data Flow Diagrams for Modelling Applications using XML

Author 1: James PH Coleman

Data Flow Diagrams were developed in the 1970’s as a method of modelling data flow when developing information systems. While DFDs are still being used, the modern web-based which is client-server based means that DFDs are not as useful. This paper proposes a modified form of DFD that incorporates, amongst… Read full abstract & cite →
