Business layer role in data retrieval - criticisms please
Hi, I'm writing a 3 tier product that is set to evolve in functionality over
several years as more modules are developed and optionally integrated. I
therefore need an easily maintainable and manageable design model.
I have a root object in the data layer that deals with all data retrieval
requests and returns typed datasets.
I have a root object in the business layer that does the same.
It seems like a good idea to derive the BL root from the DAL root and
override/add methods to the BL root accordingly.
Does anyone have a good counter argument
