that's right .. I personally also recommend simply using a single primary key 
which is entirely decoupled from any business attributes/objects



Hibernate also recommend this strategy, and AndroMDA works optimaly when 
working this way



for example, the CRUD feature which generates an entire application to manage 
your tables: 

can't handed these primary keys



it's just that if you start down that road things become unneccesarily complex
