Persistency handles the storage and retrieval of data from file. The Persistency package makes significant use of ROOT persistency tools, including its streaming mechanism, automatic schema evolution, file management, data structures (TTree), remote file access (TNetFile & TAuthenticate), and persistable pointers (TRef).

User Interface

Persistency is a low level package and the user doesn't generally need to use its interface directly. Persistency lies underneath the IoModules package and the user controls I/O through the IoInput & Output job modules.
