The document discusses the Object Data Manager (ODM) in AIX. ODM maintains system configuration by saving everything in binary format for security rather than ASCII. It is more robust and secure. ODM manages data by storing configuration files and repositories in locations like /usr/lib/objrepos and /etc/objrepos. Similar to entries in /etc/passwd, ODM uses a component-based structure. Commands like odmchange, odmcreate, odmdelete allow users to manage objects and object classes within ODM.
