....collections of small database objects in an efficient way through the ORB transparently to the clients. This issue is currently addressed in the new CORBA Portable Object Adapter (POA) specification [Schmidt Vinoski 97, OMG 98b] the proposal for the new CORBA Persistent State Service (PSS) IONA et al. 98] and in the standard specifications from the object database community s counterpart to OMG; ODMG (Object Data Management Group) Cattel Barry 97] One solution to this problem is to let the object implementers decide which subset of database objects that should be accessed directly as CORBA ....

....These circumstances lead to the fact that only certain parts of the distributed objects should be made persistent, i.e. represent the state. So, which components of a CORBA object represent state This is currently dealt with in a standard proposal to the OMG for passing objects by value 1 [IONA et al. 98] It contains an extension of the IDL so that the state of an object can be defined explicitly. This is for instance useful for caching purposes; the local object cache can first request the remote object by value and then store its state locally. In chapter 6, this process is called localize. ....
