Explain the design steps in transaction mapping.
- Review the fundamental model.
- Review and refine the DFD for the software.
- Verify whether the DFD has the transform or transaction mapping.
- Identify transaction center and the flow characteristics along each of the action paths.
- Factor and refine the transaction structure and the structure of every action path.
- Refine the first iteration architecture using design heuristics for improved software quality.
