Network management stations use SNMP to retrieve or alter management data from network elements. A datum of management information is called a managed object; the value of a managed object can be static or variable. Network elements store managed objects in a database called a management information base (MIB).

MIBs are hierarchically structured and use object identifiers to address managed objects, but managed objects also have a textual name called an object descriptor.
