A nested group is a group within another group. A single element within the first group (the “parent” group) is actually another group, a “nested” group. In Figure 1-11, “b” is a single element in the parent group. It contains two separate pieces of data, “x” and “y,” which are the nested group.
Figure 1-11: Incoming transaction nested group
An example of data that fits this example is a parent group containing the elements item_number (“a”), description (“b”), and amount (“c”). The description element contains within it a nested group consisting of a color (“x”) and a size (“y”).
