Tutorial for Designer/2000
and Developer/2000


Lesson 3, page 4

  1. The Process Modeller does not automatically show the name of the flows on the diagram. To view the names ( for example, student_request):

  2. Your process model should now look like Figure 3.19.

    Figure 3.19

    Figure 3.19: The process model with the first process flow label

  3. Using step 16 create the following dataflows:

    The updated process model is shown in Figure 3.20. Note that you will have to rearrange the positions of the processes and datastores (by dragging, and in some instances, by cutting and pasting) in order to create a satisfactory layout. Your completed process diagram, thus, could look somewhat different from the Figure 3.20.

    Figure 3.20

  4. To view your diagram in iconic mode, select Iconic from the View menu as shown in Figure 3.21.

    Figure 3.21

    Figure 3.21: The View Drop-Down Menu

  5. You will now the see your diagram in the iconic mode. (See Figure 3.22).

  6. Save your diagram as File-> Save As SRSPD.
By now, you must have realized that the Process Modeller (that creates process models) and the Dataflow Diagrammer (that creates the data flow diagram) are quite similar. You may be wondering what the differences between the two tools are. The following table adapted from Dorsey and Koletzke (1997) points out some of the similarities and differences between the two. Knowing the differences could help you decide when a particular tool is more appropriate than the other.

Task Process Modeller Dataflow Diagrammer
Shows Organization Units on the Diagram Yes No
Distinguishes between processes, flows and stores Yes Yes
Define triggering Events and Outcomes Yes (not covered in this introductory tutorial) No
Represent Entities external to the System Yes Yes

Lesson Summary:

In this lesson you have learned the basics of how to create Process Diagrams using the Process Modeller. You should now have the necessary skills and experience to create:

Our next lesson will focus on functional hierarchy diagrams. For this, proceed to Lesson 4.
