I've been looking for a site or a book where to learn CMR but I'm getting crazy, all the examples are too long and complicated for me to understand.
Why do I need CMR?
Well, I have two tables in my database: Tickets and Concerts. If I want to calculate the number of tickets demanded for one concert .. I suppose I need to relate Tickets and Concerts beans .. but how? What fields should I create in the tables?
I'm starting to use jBuilder and creating the relationship, once I understand what fields I have to use, is not a problem but what is a mystery to me is: after creating the fields in database and the relationship in between the beans, what's next? which is the code I have to use in the servlet in order to manage the relationship? And what about the transactions? How are they used within CMR?
Thanks a million in advance
