>Say you have a parts stock room system. I have a class that is used as BIZ object for validating entries in the parts stock room table. Another typical thing that has to be done in this system is posting receipt of some quantities for the parts. In the UI tier this is done in a batch mode: User has a grid-like form where he/she enters a bunch of parts and the QTY received for each part. This UI tier will then pass the information to the BIZ object that will update (via DA tier) the in-stock quantities. My question is, do I simply add a method of batch posting of receipt items to the Stock Room Parts BIZ class or is it better to have a separate class for using with batch processing?

I'm not sure if this is the best or correct practice, but I was having two types of objects.

One is session based object which was based on my BusinessProcess class. I handled all complex logic in that class.

The other biz object was more of one record in a time processing and it was based on MereMortals biz object.
