At a very abstract level, yes. But it doesn't have to be in memory. It can be on disk, or it can be a view of data represented in some other way (e.g. tables in an RDBMS). It doesn't even all have to exist at the same time, that is, it can be a transient stream of SAX events. > > The data model instance is represented by a set of data > structures, in say a JVM space. > > Am I correct in saying so?
