Quick review this week with a number of assignments still on the ‘to-do’ pile.
Week 9 -> Structured Design.
We jumped out of the Object Oriented development methodology to take a look at the Design phase in the eyes of a traditional Systems designer. What we saw:
- System Flowchart – Need system boundaries in Design phase.
- Structure Chart – Describes processes in the System Flowchart in more detail using transaction analysis.
- Module Pseudocode – Describes internal logical of Structure chart modules
- Three-layer architecture – Structure charts may be based on this architecture (Data Layer -> Business Logic Layer -> View Layer)
Pearl of the week: The Analysis – Design conversion for Structured/Traditional Development methodology is a process of exploding the DFD from the Analysis phase.
