Draw an FDD that shows the Personal Trainer’s main functions. Also draw a use case diagram that represents the interaction between a user and the proposed TIMS system.
What will be an ideal response?
FDD drawings will vary but they should show a hierarchy of major functions and processes, as described in the chapter.
There is no standard answer for this use case example. In most cases, students will suggest a use case diagram similar to the basic examples shown in the textbook. You should remind students that the topic of UML and object-oriented analysis is covered in more detail in Chapter 6.
Stress that in a use case diagram, the user becomes an actor with a specific role that describes how he or she interacts with the system. Note that systems analysts can draw use case diagrams freehand or use CASE tools that integrate the use cases into the overall system design.
