Unified Modeling Language (UML) Chapter 20 Unified Modeling Language (UML) Sharif University of Technology, International Branch, Kish Island Dr. Mohsen Sadighi Moshkenani www.sadighim.ir

Outline Recall model and modeling (Chapter 12) UML Different diagrams www.sadighim.ir

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 www.sadighim.ir

Modeling and design www.sadighim.ir

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 www.sadighim.ir

Why model and modeling www.sadighim.ir

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 www.sadighim.ir

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) www.sadighim.ir

Notation for class and object representation www.sadighim.ir

Class relations (Cont.) Association Inheritance Aggregation and Composition www.sadighim.ir

Class relations www.sadighim.ir
