Tutorial for Designer/2000
and Developer/2000

Lesson 4, page 4

  1. You can also view your diagram in three different ways: horizontal, vertical and hybrid (combination of horizontal and vertical format). Figure 4.10 in the previous page is in Horizontal Layout. To view it in different modes, select the respective mode from the Layout Menu. (See Figure 4.11 for how to select a vertical layout).

    Figure 4.11: The Layout Drop-Down Menu

  2. Figure 4.12 shows part of the diagram in vertical layout. You will have to scroll down using the side scroll bars to see the full diagram in vertical layout.

  3. Figure 4.13 shows part of the diagram in hybrid format. You will have to scroll down to see the full diagram.

  4. You can also select a particular function by clicking on it and cause them to be in a horizontal or vertical layout irrespective of the layouts of the other functions. To do this select a particular function, for example SRS2 and select Vertical Layout Selection from the Layout Menu. (See Figure 4.14).

  5. You will now see your diagram with two functions in horizontal mode and one in vertical mode. (See Figure 4.15).

  6. Do not forget to save your diagram from the File -> Save Diagram As FHDSRS.

Lesson Summary:

In this lesson you have learned to create a Function Hierarchy Diagram. You should now be able to:

Next, we will learn how to create an ER model using the ER Diagrammer. For this, proceed to lesson 5.
