Tree Labels
Tree labels are tags that are stored on tree nodes. You can store labels in any table and register the label data source with the tree structure.
When a labeling scheme is used for trees, the selected labels are stored in the tree label entity, and each tree node contains a reference to a tree label in the labeling scheme. The following table lists the three ways in which tree labels are assigned to the tree nodes.
| Labeling Scheme | Description | 
|---|---|
| Level | Labels that are automatically assigned based on the data source to which the tree node belongs. A level label points to a specific data source. For example, in a tree that reflects the organizational hierarchy of an enterprise, all division nodes appear on one level and all department nodes on another. | 
| Group | Labels that you can arbitrarily assign to tree nodes. | 
| Depth | Labels that are automatically assigned based on the depth of the tree node within the tree. No manual assignment is performed. Note: 
                         In an unbalanced hierarchy, a level may not be equal to depth. |
