Tracy,
In your initial message you mentioned (if I remember correctly) that most of your study is to decide on approach of UI -> MT -> Database. I was wondering (I apologize if you already talked about it and I missed it) if you are planning your future application UI to be in Win Forms (windows) or Web Forms (ASP)? I am kind of sort of going through the same process in my head for my application, and for me a major decision is what to user for UI: WinForms or WebForms. I am changing my mind (conceptually) back and forth every day <g>.
