Database which allows object to be "child" of any other object

I'm working on a database-driven project and I'm trying to do some re- architecting of the system.

I would like to cut down on the number of strictly-defined complex object types, instead forming them from a composition of attached atomic metadata objects. A user could have an attached phone number, an attached address, an attached photo; but furthermore, an address could have an attached photo or phone number.

This means that in the DB, my relationship cannot be simply from the "PhoneNumber" table to the "User" table. It must allow relationships from each metadata table to, potentially, every other metadata table. This **could** be done using n^2 association tables for each parent/ child combination of metadata tables, but that would suck major donkey balls. It could also be done by having a generalized association table which specifies both the table *and* the key of the parent and child in the relationship, but I can think of no way to set up automatic referential integrity checking when doing this.

My questions are:
