The Persistent State Service (PSS) is designed to be a CORBA-friendly form of persistence management. The PSS superceeds the POS.
Unlike the POS that attempted to provide both a client IDL interface for persistence control and a server-side layer for allowing CORBA implementation objects to save their state, the PSS focuses on only the latter.
At a high-level the PSS is an IDL defined abstraction layer of data storage. It needs to be implemented for a particular datastore, such as a file system, a relational database, or an OODB. This allows CORBA implementation objects to be abstracted from their storage mechanisms, much like ODBC/JDBC abstract relational databases.
