Reshaping and Restructuring Can Move Fragments

We saw in the previous example (Figure 2) that the Department and Employee nodes were already correctly positioned at their top structure copy level. Their correct positioning was utilized avoiding the separate movement of the Employee node data. This can also occur when accessing lower structures as in the example in Figure 3.

In this case, only the Employee node in the target structure is in correct positioning at the top structure copy. But it turns out the Department and Project nodes are already in position (Project node under Department node) in the lower level structure copy and can be moved together as a structure fragment preserving the current relationship.
