On Opie we simply call that X-Ref ( Cross Reference ). You can identify any
record on a Opie System with a uid and an appname additional you can also
link a TableField with a record or another records table field.
For example the birthday of your spouse could be linked to the vCard of your
spouse.
We've a libopie which takes care of the basic X-Ref and PIM Stuff. It's
designed to have possible multiple backends (XML, sqlite, oracle,
vCal/iCal... ) and to give common access to our applications like todolist,
contatcs and datebook.
It can be found at libopie/pim.
We try to delay the loading of records as much as possible. this is magically
done through c++ templates. To not need to reload every time we do caching
and read ahead too ;)

PS For more informations I'm glad to help.
