Terms are a crazy thing, everyone seems to want to use the ones they 
like the most any way they like.

Personally I prefer the terms;

   - Storage Objects, or Database Objects
       for objects that are built around the Database structure, such as
       Class::DBI, Alzabo, DBIx::SearchBuilder, SPOPS, etc.

   - Object Persistence
       for orthogonal systems that don't touch the objects they are
       storing in any way, except perhaps via magic references.  This
       includes Pixie and Tangram.

I think "Object Relational Mapping" does not imply either of these; an 
Object/Relational mapper could work in either direction and is a good 
blanket term to describe both.

The latter term might seem a bit close to "Perl Object Oriented 
Persistence", but they are not quite the same thing, as "Object 
Oriented" refers to a quite different idea than "Object".

If anyone has any suggestions for better terms, or objections to these 
terms, please feel free to raise them now.

Sam.
