In the words of Dr Evil - "Pretty standard really". That's not meant to be an
insult either. Many people are using that same architecture now; if implemented
correctly it presents a very nice implementation of MVC. I will direct my words of
caution to your work with the persistence layer. Spend some time here doing very
careful analysis. Read as much as you can about mapping objects to relational
databases (I am assuming you are using a relational database). I recommend
(http://www-106.ibm.com/developerworks/library/mapping-to-rdb/) or anything by
Scott Ambler.
Good luck.
