1. In the name of God Sharif University of Technology, International Branch, Kish Island Dr. Mohsen Sadighi Moshkenani www.sadighim.ir Chapter 20

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 (www.omg.org)

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

13. Read a sample class diagram نام نمودار نقشمثال كلاس نمايش كلاس ‌ ها و روابط بين آن ‌ ها

14. Read some sample class diagram

19. Read a use case diagram نام نمودار نقشمثال مورد كاربرد براي بيان مخاطبان سامانه و انتظاراتي كه اين سامانه در قبال هر مخاطب برآورده مي ‌ كند Read some sample class diagram

21. Collaboration diagram نام نمودار نقشمثال همكاري نمايش مصداقي از همكاري شيءها با يكديگر

22. Sample sequence diagram نام نمودار نقشمثال ترتيب نمايش مصداقي از همكاري شيءها با يكديگر و توجه روي ترتيب زماني

23. Read a sample state diagram نام نمودار نقشمثال حالت نمايش حالت ‌ هاي مهم و تغيير حالت ‌ ها در زندگي يك شيء

24. A sample activity diagram نام نمودار نقشمثال فعاليت براي بيان فعاليت ‌ هاي عوامل درگير و ترتيب و همزماني اين فعاليت ‌ ها

26. A sample package diagram نام نمودار نقشمثال بسته نمايش بسته ‌ ها، به ‌ عنوان بخش ‌ هاي اصلي سامانه و ارتباط بين آن ‌ ها

27. A sample deployment diagram نام نمودار نقشمثال استقرار نمايش استقرار جغرافيايي بخش ‌ هاي مختلف يك سامانه و ارتباط بين آن ‌ ها

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 CompareCompare 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).UMLuse case diagramclass diagramcomposite structure diagramobject diagramsequence diagram communication diagramactivity diagramstate machine diagramtiming diagraminteraction overview diagramcomponent diagram deployment diagrampackage diagram requirement diagramCRC card diagramentity relationship diagram (ERD)

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