  • Publication number: 20230206349
    Abstract: To answer if a user is a transitive member of a group efficiently, a method to maintain each node's ancestors or descendants is disclosed. The system maintains each node's ancestor paths or descendant paths and update affected nodes when a child node is added to or removed from the parent node. The affected nodes are the child and the child's descendants in the case of ancestor paths. The affected nodes are the parent and the parent's ancestors in the case of descendant paths. The node's ancestors or descendants are the unique nodes in the ancestor paths or descendant paths. Hybrid approaches can be used to reduce change volumes by skipping users.
