Developing a Structure Chart

Two approaches that can be used to develop a Structure Chart are Transaction Analysis and Transform Analysis (Satzinger 2007).

Transaction analysis

  • Uses system flow chart and event table inputs
  • Upper-level modules developed first
  • Identifies each transaction supported by program

Transform analysis

  • Uses DFD fragments for inputs
  • Computer program “transforms” inputs into outputs
  • Charts have input, calculate, and output subtrees
