<model name>_NODES table
This table contains all tree nodes in the model, the parent node for every node, and explanatory information.
The table contains one line for each tree node.
The following table shows the table columns:
| Column | Data type | Description |
|---|---|---|
| NODEID | BIGINT | Index value of the node in the tree model The root node has the NODEID 1. |
| NAME | VARCHAR(100) | Name of the node The default value is NODEID. |
| DESCRIPTION | VARCHAR(10000) | Textual node description The default value is NULL. |
| SIZE | DOUBLE | Number of data records in the node |
| RELSIZE | DOUBLE | Relative size of the node, that is,the size of the current node divided by the size of the root node (NODEID 1) |
| ISLEAF | SMALLINT | Indicates whether the node is a leaf node |
| PARENT | BIGINT | NODEID of the parent node |
| CLASS | VARCHAR(40) | Prediction for records in this node |
| IMPURITY | DOUBLE | Class impurity measure of this node |
| DEFAULTCHILD | BIGINT | NODEID of default child node If the predicate cannot be evaluated, this node is used as the successor. If the MISSINGVALUESTRATEGY parameter is not DEFAULTCHILD, this value is NULL. |
