Hi Thomas
Thanks for the quick response. OK, how would you suggest I solve this
scenario:
I have 2 tables: Person and Address.
For every person, they are associated with an address. Loading persons would
be ok. What if I now want to list all the addresses in the Address table? I
have to traverse the person's table and extract the address?

Dependent object cannot be created/removed explicitly. It's created
automatically when it is added to a master object, and removed automatically
when it de-linked/dereferenced from a master object.
Otherwise, we will be run into problem likes a dependent object created
explicitly but removed implicitly (delinked from a master object), or vice
versa, and other problems that is harder to detect.
