Behavioral Modeling

The next few sections present solutions for Part III.

Chapter 6

1. Figure B-32 shows the sequence diagram, and Figure B-33 shows the collaboration diagram. The interaction and collaboration is that of the Generate Project-Status Report described in Chapter 6.

   In Figure B-32, the following elements are missing:

   • ELM-01 should be:

     4 : OutputData := FormatInfo (OrgInfo, PrjInfo)

   • ELM-02 should be:

     12 : OutputData := FormatWorkerInfo (UnitsOfWork, WorkProducts)

   • ELM-03 should be:

     [No more workers]

   In Figure B-33, the following elements are missing:

   • ELM-04 should be:

     [Populated Project] 7 : GenerateReport(  )

   • ELM-05 should be:

     *[For each worker] 7.2 : outputWorkerInfo (Worker)

   • ELM-06 should be:

     9 : Destroy (  )

2. The following describes the figure: there are three elements, named Section, Report, and OutputDeviceInterface. The Report element has a Use relationship with the OutputDeviceInterface element and a Has relationship with the Section element.

   Because these figures show an interaction and collaboration, each step adds to the previous step; otherwise, the notion of when a communication occurs would be lost!

   1. Figure B-34 and Figure B-35 show the figures.
