Tree Nodes

Tree nodes are points of data convergence where a tree branches into levels. Nodes are the building blocks of a tree structure and are attached to tree versions.

Whenever you create or edit a tree version, you need to specify its tree node. To manage tree nodes, in the Setup and Maintenance work area, go to the Manage Trees and Tree Versions task.

Managing Tree Nodes

You can create, modify, or delete tree nodes on the Tree Version: Specify Nodes page. To add a tree node, ensure that the tree structure with which the tree version is associated is mapped to a valid data source. You can also duplicate a tree node if the multiple root node feature is enabled.

Node Levels

Usually, the nodes at a particular level represent similar information. For example, in a tree that reflects the organizational hierarchy, all nodes representing divisions appear at one level and all the department nodes on another. Similarly, in a tree that organizes a user's product catalog, the nodes representing individual products might appear at one level and the nodes representing product lines on the immediate higher level.

The following node levels are in use:

  • Root node: The highest node in the tree structure

  • Parent node: The node that branches off into other nodes

  • Child node: The node that's connected to a node higher in hierarchy (parent node)

  • Sibling node: Nodes that are at the same level and belong to the same parent node

  • Leaf node: Entities branching off from a node but not extending further down the tree hierarchy

Node Types

A tree node has the following node types.

  • Single: Indicates that the node is a value by itself.

  • Range: Indicates that the node represents a range of values and possibly could have many children. For example, a tree node representing account numbers 10000 to 99999.

  • Referenced Tree: Indicates that the tree node is actually another version for the tree based on the same tree structure, which isn't physically stored in the same tree. For example, a geographic hierarchy for the United States can be referenced in a World geographic hierarchy.
