Described is a method for storing tree structures that can be expressed as DAGs that: (1) reduces storage requirements; (2) facilitates fast identification of nodes (locations) where changes have been made during an update; and (3) only allows users with appropriate levels of authorization to view database contants, as well as node (e.g., document category) names.
