I don't do a lot of n-tier development with web services, but you are saying that the web service is between the UI and Biz, not Biz and Data, or Data and Database?

>I only asked about the Web Services because you'll have to change the code in the UI layer once you start using them. The UI will call a Save Web Service method, which will then call the Save in the Business layer, etc. You probably already figured that part out though.

>>Yes, we are planning on using Web Services. What I am trying to do right now is to understand the basic 3 layers. Once I get familiar I will get involved with Web Services( I have never used one,so I do not know anything about it).
