SSADM vs UML We examine the two Methods { SSADM And UML} • In terms of their manner of handling System Elements. In each case comparisons transgress the Object vs. Non-Object oriented paradigms nevertheless the scope of the activities is similar. Renaat Verbruggen
Data/Events/Processes • 1. Data • Logical Data Model (LDM) • The class diagram • 2. Events • Entity Life History (ELH) • The Behaviour (interaction) diagrams • 3. Processes • Data Flow Diagram (DFD) • The activity diagram Renaat Verbruggen
Interfaces /Resources • 4. Interfaces • Dialogue Design • Modelled in class and component diagrams. • 5. Resources • Requirements Catalogue (RC). • Modelled by using the stereotype feature. Renaat Verbruggen
Quality / Business issues • 6. Quality • Requirements Catalogue (RC). • A. In analysis explorative prototypes. • B. In design experimental prototypes • 7. Business issues • A. Data Flow Diagrams (DFD). • B. Entity Life History (ELH). • Activity diagrams describe and model business process. Renaat Verbruggen
