BMP vs CMP with Orion

[Cory Adams]

I have looked through the 2.0 spec and find the chapters regarding CMP to
be daunting.  It appears as though the complexity of writing my own SQL in
BMP has to be balanced against learning an entire new way of managin
persistence within the XML deployment descriptors which seems to be no less
or perhaps even more complicated than BMP????

Or am I missing something with regard to CMP being easier?

Thanks,

Cory
