Represents a tree of geographic locations. This is
a relationship table of GEONODE, such as country -> state ->
city
Column Descriptions:
| Name | Type | Description |
| GEOTREE_ID | INTEGER NOT NULL | Geo tree Id. |
| CHILD_GEONODE_ID | INTEGER NOT NULL | Child geo node. Foreign key to
GEONODE.GEONODE_ID. |
| PARENT_GEONODE_ID | INTEGER | Parent geo node Id. Foreign key to
GEONODE.GEONODE_ID. if this column is null, the child geo node is
the root node of the tree. |
| SEQUENCE | DOUBLE | The display sequence. |
| OPTCOUNTER | SMALLINT NOT NULL DEFAULT 0 | The optimistic concurrency control counter for
the table. Every time there is an update to the table, the counter
is incremented. |
