Matrix Overlays

The Relationship Matrix indicates the existence of connectors between elements by displaying an arrow in the cell at the intersection of the source element row and target element column. If you prefer, you can toggle the display to become a CRUD matrix, where the presence of a connector is indicated by the appropriate value or combination of CRUD values in the intersection cell. You define the actual values that are entered and displayed, so the  characters can refer to whatever interpretation of CRUD your organization uses, or be another standard set of indicators such as BREAD, or your own custom set of indicators. The values can, therefore, be a selection of the following, or anything else you might use:

Read, Retrieve
Delete, Destroy

Toggle between the two display formats

Click on the Overlay field drop-down arrow and select either:

<None> to use the direction arrow Relationship Matrix format
The name of your CRUD overlay, to use the CRUD Matrix format, or
<New Overlay> to create and use a new CRUD Matrix overlay
