CMP is more efficient than BMP.
Facade pattern abstracts the load/insert/update/delete activities well
and let the session bean do this!
However, since the tables are linked, the queries would get a bit
complicated as you would need constraint checks and CASCADEs.
That would be tradeoff that you will have to live with!
