Hi Mimi,
CODAP shows the “parent-child” relationship in the case table with curvy lines, as you can see in the screen shot I’ve uploaded. Very useful is to click on one of the parent rows to select that row and all the child case rows. This is also shown in the screen shot. As you scroll the child table, CODAP attempts to keep the parent table in synch so you can see the parents approximately next to their children.
Another way is to make a graph (as shown in the second screen shot) in which some unique identifier for the parent is on one axis and some attribute for the children is on the other axis. Here you can easily see that the selected child case has Kentucky as its parent.
I’m not sure I’ve answered your question. Don’t hesitate to follow up!
Bill
