Transaction Mapping

Di banyak software aplikasi, sebuah singgle data item mentrigger satu atau beberapa information flow yang menyebabkan sebuah fungsi diimplied karena mentrigger data item(transaction).

Design step-nya:
1. Review fundamental system model
2. Refiew and refine data flow diagram for the software
3. Determine whether the DFD has transform or transactin flow characteristics
4. Identify the transaction center and the flow characteristics along each of action paths
5. Map the DFD in a program structure amenable to transaction processing
6. Factor and refine the transaction structure and the structure of each action path
7. Refine the first iteration program structure using design heuristics for improved software quality

Design Postprocessing

Aplikasi yang sukses melakukan transform atau transaction mapping dibantu oleh tambahan dokumentsi yang dibutuhkan sebagai bagian dari desain arsitektur. Setelah struktur dikembangkan dan di refine, beberapa tugas harus diselesaikan:
– Aprocessing narrative must be developed for each module
– An interface description is provided for each module
– Local and global data structures are defined
– All design restrictions/limitations are noted
– A design review is conducted
– “Optimization” is considered (if required and justified)
