why create related CMPs?

Hi all,
I know that when we create related CMPs it puts those methods returning Collection in one side in 1-to-N relation and etc things but I am trying to come up with more convincing reasons for need of related CMPs. Here are my thoughts so far,
1. when we create related CMPs it inserts relationship management methods automatically which could help programmers to "not worry about" foreign key constraints etc...
more input?
Regards
Maulin

Having CMR and the container to handle relationships is a great ease for a developer. I think this is enough as a reason for using relationships in CMP .


...watch me...as I'm walking the path...
 
It is sorta covered in the JavaRanch Style Guide.
