2. Outline Recall model and modeling (Chapter 12) UML Different diagrams

3. Model and Modeling Examples Model is a symbol of/for reality
Modeling is the process of imagination and creation of a symbol (model) of/for reality, from specific view point
In analysis we model the related real available world
In design we model the related interested future world

4. Modeling and design

5. Why model and modeling Model is a simplified reality
Unnecessary details are kept hidden
Causes better understanding of problem and possible solutions
A chance to see different solutions
Simple, fast and cheap
Visualization of ideas
Chance for evaluation

6. Why model and modeling

7. Role of object model Object model simplifies the modeling process
Recall OO principles (Chapter 19)
Object model (in compare with other software models) has the most compatibility with real world

8. UML to representation model
Why the model should be represented?
Try to visualize the model
Unified Modeling Language (UML) is well known (standard) means for visualization
UML defines a set diagrams to model the real world
Now UML works as a standard to represent models; much beyond software engineering and IT
Object Management Group is the root point for UML (

9. Notation for class and object representation

10. Class relations (Cont.)
Association
Inheritance
Aggregation and
Composition

11. Class relations

12. Class diagram Visualize your analysis and design
Class diagram represents classes and their relations
You may have many class diagrams

28. Use Tools There are too many supporting tools
HW: Select a UML tool. Provide 3 different diagrams (for next week)

29. Visual Paradigm for UML 8.1 Community Edition Compare
Visual Paradigm for UML Community Edition (VP-UML CE) is a feature rich, FREE UML tool which supports all kinds of UML diagrams. Here are the diagrams you can draw with VP-UML CE: use case diagram, class diagram, composite structure diagram, object diagram, sequence diagram, communication diagram, activity diagram, state machine diagram, timing diagram, interaction overview diagram, component diagram, deployment diagram, package diagram, requirement diagram, CRC card diagram and entity relationship diagram (ERD).

30. Too many samples Search for UML samples within images
You may search for a special UML sample diagram
