UMLBased Design Enviroment for Interactive Applications

1
UML-Based Design Enviroment for Interactive
Applications
2
UMLi

• The Unified Modelling Language for Interactive
  Applications
• An extension of UML
• Easing the design of user interfaces
• Emphasises on supporting the development of
  form-based interactive interfaces
• Enviroment tool ARGOi
• Relation between interaction and domain objects

3
Modeling User Interface Presentations

• UML Class and object diagrams
• Problems Identifying roles and containments

4
User Interface Presentations
5
Modelling User Interface Behaviour

• Control-flow and data-flow
• Difference lies in whether the activity diagram
  has object flows or not.
• UMLi has distinct facilities for modelling
  control-flow and data-flow.

ARGO
8
ARGOi

• Based on ARGO and provides the UMLi facilities.
• Based mainly on the extended functionalities
  implemented in the editing panel and property form

9
ARGOi high level architecture

• Components (ARGO, GEF, NSUML,XML Parser)

10
Presentation Modelling Support

• Problems (content, concept)
• ARGOi (FreeContainer, automatically created)
• Interaction objects (constructor creators,
  placement, layout)
• From abstract presentation to concrete
  presentation

11
Control-flow Modelling Support

• Temporal-relation wizard
• Based on task model techniques
• Uses extensions to UML activity diagrams
• Benefits
• Reduced effort modelling control-flow
• Exploits the potential of SelectionStates and
  ReturnTransitions

Data-flow Modelling Support

• Classifiers (Class, UseCase, InteractionObject)
• Type specification
• Stereotypes

Conclusions

• UMLi can be effectively implemented in a
  UML-based design environment
• ARGOi can provide support for modelling a
  complete interactive application
