PeopleSoft Tree Manager 3: Terminology

Tree: A tree has a hierarchical structure. A tree is like the organization chart. It is visual representation of a set of values that are related to each other for the purpose of summarizing and security.

Node: The element within the tree. A tree is made up of nodes.

Root Node: Each tree has one and only one root node. A root node is the first node in the tree. The highest level for rollup.

Parent Node: It is any node has at least a child node. A root node is always a parent node unless there is no other node in the tree.

Child Node: All nodes are child node except the root node.

Sibling: Sibling are nodes at the same level.

Detail Values: Detail Values are always at the bottom of the tree. The tree can be used t summarize the data associated with the detail values. The detail values can be assigned to the tree nodes using the range of values. You can also assign individual values.

Levels: logical grouping of nodes. for example, State, country and regions. Tree manager can enforce the integrity. The use of level is not required. However, once you decided that you are not using levels, you cannot add levels back. When you create the tree by adding nodes to the tree, you add levels from top down.

Tree Structure: it defines which pages, record, and fields are used

Relationship: A relationship within a tree is a parent child relationship. A relationship includes two node, the one closer to the root node is the parent node and the other one is the child node.
