Managing Data with Data Tunneling
In the first part of this chapter, you learned how to manage data that’s in a table only one relationship away from your source table. For example, earlier in this chapter, you learned how to create line items through a portal in an invoice record. (Remember from the graph in Figure 8-13 that the Invoice table occurrence is directly connected to the Line Items table occurrence.)
But you can also manage data that’s stored farther away on the relationships graph. For example, your Invoice table occurrence is also related to the Expenses table occurrence all the way on the other end of the graph because there’s a continuous line of table occurrences connecting them through their respective relationships (Figure 8-16). Even though they aren’t directly connected, you can still work with data that’s several TOs away from your current table.
