Discuss in details the design steps in transaction mapping.
- Re-Check the fundamental model.
- Re-check and refine the DFD for the software.
- Determine the DFD has either the transform or transaction mapping.
- Identify transaction center and the flow properties along with each of the action paths.
- Factor and refine the transaction structure and the structure of each action path.
- Refine the first iteration structural design using design heuristics for improved software quality.
