11.2.4 Federated name space
All name servers with a cell are federated into the cell name space. Every appserver process contains a name server. All name servers provide the same logical view of the cell name space. The various server roots and persistent partitions of the name space are interconnected by a system name space. Use the system name space structure to traverse any context in the cell's name space.
The name space can be broken down into distinct partitions that are updateable and persistent.
