Question

Any idea how I can relate different objects together? Usecase i am trying to achieve is Comments are usually owned by a user. So i have a user_id for it. But I have company pages also where the company owns the content on its page so the owner is the company_id. (Which ofcoure is admin by several users)

One way is to have 2 tables user_comments and company_comments but the problem is then i need 2 tables per object and if i add more user types then i need to multiple the tables. What i want to achieve is 1 table which has:

comment_id PK  
owner_id (user id or company id or etc...)  - fk?

So let’s say i create a owner table just to link all user types together, what would the columns be to get these all in or is there some other way?
