Hi Lvjing,
From reading your posts, I think probably the best thing to help you would be to engage Delacor or a DQMH Trusted Advisor to help with your application.
The DQMH Trusted Advisors can do personalised online DQMH training, where they will teach you how to use DQMH but also apply it to your specific needs.
I personally did this 3 years ago, and it made a world of difference. The end result was we learnt DQMH in a deep way, and we had a very well architected application.
