Just inquiring further. It further means that it's actually your database which is your BLL (by definition), since any special circumstances you want to make will have to be made in there without disturbing the reflection. Or you end up subclassing one of your entities in order to override certain methods to perform any validation that you may some day need.

Now instead of getting more pointers, how about answering some questions? What changes do you anticipate in the future? What are you looking for with this design?
