Question from Chapters 5,6,7,8
1. What UML diagram types do you need to represent the essential features of a system?
A. Activity diagrams, which show the activity that make up a system process and the flow of control
B. Use case diagrams, which show the interactions between a system and its environment.
C. Sequence diagrams, which show interactions between actors and the system and between system components.
D. Class diagrams, which show the object classes in the system and the associations between these classes.
E. State diagrams, which show how the system reacts to internal and external events.
5. System model
2. What is described in a context model? Business process models are used along with other models by simple …show more content…
What is illustrated in a UML sequence diagram?
Interactions of the sequence between the system ‘s environment actors and systems objectives .interaction of a sequence describe function of a system , feature of system and system implementation
5.3 system model
6. How is generalization used to simplify the models of a system with many similar objects?
Common attributes and methods of similar objects should be considered
Super class contain attribute and method
Superclass generalizes all the object sharing methods and attributes .particular object class declare attributes and methods particular they inherit the general attributes/methods from the super-class. The superclass, such as an attribute that maintains the frequency of data collection.
Superclass, which defines the common features of all instruments, such as an identifier, and get and test operations .subclasses inherit the attributes and operations from their super classes 5.3 system model
7. What is the basic assumption that underlies event-driven
