I remember seeing this question asked on another forum some time back. I dont like the solution the guy had and Im wondering how some of you might solve problem. Im giving a low level generic example.

Lets say you have a parent-child relationship. The parent table is 'TRUCKS' and the child table is 'CARGO'. The foreign key to CARGO tells which truck the cargo is loaded on. When the cargo is moved to another truck, the foreign key is updated.

I dont like this approach. it causes contention. what is a better way to design this?
