Forms should not connect directly to the data, but should go through a biz object. See:

>I'm writing an application right now, and I'm trying to get a hold on best practices or a standarad for good architecture of a program. The way I have it right now is:
>
>forms -> DataAccessLayer(creates stored procedures,sql commands) or ->BusinessLayer(functions to determine tax) ->DataAbstractLayer(which is a reader, and a dataset, that takes a command and returns whats needed) -> DataLayer(sql server)
>
>Is this good architecture or is it missing something?
