"Mastering Enterprise JavaBeans 2nd Edition" written by Ed Roman
(PDF file of this book is freely available from
http://www.theserverside.com//books/masteringEJB/index.jsp)
has an excellent chapter (Chapter 11: BMP and CMP
Relationships) on Relationship on Entity beans including
aggregation and composition (page 350). And explanation on
