Relationship Information

Information about all links between each set of nodes composes a relationship. This information describes the aggregate association between the nodes and is automatically captured for each link in a network. Table 15 provides the column name and definition of the captured relationship information. Column names are not relationship information but IDs of the linked nodes and the link summary ID.

Table 7-6 Relationship Info in the KDD_LINK_SUMMARY Table

Column Name	Description
