Why? Oracle has had this model for more than a decade and it has never caused anyone a problem. Which, I would think, would make you consider that maybe the problem is in your design requirement.

Why not avoid the wasted effort creating a performance and scalability killing kludge and just present the business problem you are trying to solve?
