  You raise an excellent point, however, using a conventional relational
DBMS is not going to be the way to go.  What you are talking about is
exactly what object databases are meant for.  Unfortunately, we are all
waiting for someone to write a usable ODB.  Given the amount of effort
by companies like IBM and HP, they can't be too far away.  

   ODB research has more or less come to the conclusion that relational
DBMS's do not provide the required performance levels to serve as the
basis for an ODB; otherwise I suspect that ODBs would already be around.
