Tutorial for Designer/2000
Lesson 7, page 4
- Next, click the column tab to select the properties for the column elements. The column will be displaying the entities, so we select the name, short name and the maximum length for the entities. (See Figure 7.14).
Figure 7.14: The Settings Window with the properties for the column elements.
- Now click the tab for the intersection cells of the row and the column. Check the function name, entity name and the CRUD properties and click OK. (See Figure 7.15).
Figure 7.15: The Settings Window with the Intersection properties
- Once you click OK you will be able to see the matrix diagram on the screen. (See Figure 7.16).
Figure 7.16: The matrix diagram viewed in Standard Form
- You can select other views of your matrix diagram. For this select the Iconic mode from the view menu. (See Figure 7.17).
Figure 7.17: The View Menu
- You can now view your diagram in Iconic mode. (See Figure 7.18).

- At this point save your diagram by File Save Diagram as MXDSRS.
- To complete the matrix, go back to the Function Hierarchy Diagrammer, and create entity-usages for all the remaining functions (we had specified entity usages for just three functions). After saving the function hierarchy diagram with entity usages specified for each function, invoke the matrix Diagrammer, and use steps 9 -18 to create your new matrix diagram. You will see the complete CRUD matrix.
In this lesson you learned to create a matrix diagram. Specifically, you learned:
- What is a matrix diagram
- Specifying Rows and column elements in a matrix diagram
- Selecting properties of the row and column entities
- The CRUD properties
- Creating the matrix diagram
- Viewing your diagram in multiple modes.
Next, we will learn how to use some basic features of Developer/2000. For this proceed to Lesson 8.
