Object Oriented Analysis and Design Tutorial – Week 4&5 – Chapter 5 End of Chapter 1. Why is occupation course modeling dignified? 2. What is the aim of a fork node? 3. How do you imagine use instances? 4. How do you imagine use instance diagrams? 5. Yield two examples of the apply denominations on a use instance diagram. Yield two examples for the enclose denomination. 6. What is the aim of an disposition diagram? Your Turn 5-2 Use Cases Look at the disposition diagram for the provision scheme in Figure 5-2 and the use instance that was imagined in Figure 5-5.
Create your own use instance established on an disposition in the disposition diagram or the disposition that you imagined in Your Turn 5-1. Use Figure 5-6 to lead your efforts. 5-3 Use Instance Diagram Look at the use-instance diagram in Figure 5-10. Consider if a use instance were added to suppress unrepining insurance notice.

They then adjunction the chamber owners undeviatingly to see the chamber and maybe schism it. Chamber owners fawn the labor to delete their listing when they feel schismed their chamber(s). 5-6 Drawing a Use-Case Diagram In Your Turn 5-5, you identified use instances for a campus housing labor that helps students discover chambers. Established on those use instances, imagine a use-instance diagram. Exercises
A. Imagine an disposition diagram and a set of element use instance descriptions for the course of buying glasses from the viewpoint of the unrepining, but do not twainer to establish the progress of events among each use instance.
