Table 7.1, "Choosing between CMP and BMP", leaves out the most egregious
limitation of CMP: you cannot use CMP if your object spans multiple tables.
CMR might take some of the sting out of this, but it still leaves your objects
tightly coupled to the underlying database schema.

Actually, the spec. does not specify this. Some containers do support it.

Thanks for your comments. It is fairly limiting, especially if you don't
control the data model.
