DB_DataObject linking: is it only good for single row joins?

I have a table called member and another called email. The basic idea is that each member can have one or more emails. I'm using DB_DataObject and am beginning to think that it's facilities for links and joins is only useful for single row joins. Is this true or am I just not understanding the documentation? If this is the case I'm wondering what my options are and if others have advise. I suppose I could override the constructor of member to assign an array variable inside of the member, with a listing of the email_ids I'll need later in the script.
