Access to Objects is always controlled through security groups. With rare exceptions, only NetDB administrators update NetDB objects. A node is an Object, an interface is not - it's just part of a node. Other words were considered and rejected for similar reasons. The following is a list of NetDB Objects and objects as taken from the logical data model after it was revised to reflect the current physical model.
Cardinality reflects the logical data model.
Application enforced business rules may affect the cardinality seen by the user. For example, networks might be limited to a single name. This object is not fully defined.
