3-tier architecture is standard and has a higher level of manageability than say a 4-tier. Before I go off on a tangent I want to make sure we are on the same page. 1-tier Architecture Tier 1 - Everything 2-tier Architecture Tier 1 - Client Tier 2 - Database 3-tier Architecture Tier 1 - Client (Browser or Application) Tier 2 - Web and Application (Full J2EE Server) Tier 3 - Database 4-tier Architecture Tier 1 - Client (Browser or Application) Tier 2 - Web (Servlet/JSP Container) Tier 3 - Application (EJB Container) Tier 4 - Database Do these match your definitions for the different tiers?

Chris, Thank you very much for this, but what are the benefits and drawbacks of each architecture in terms of their Quality of Service (QoS) requirements? Thanks very much! Seid
I researched this. On the yahoo site or the JR somebody talked about Sun's codecamp. On Sun's site I found a codecamp document. An early chapter was helpful in understanding some of these issues. I still only scored 66% on common architectures and concepts. This is a hard area to find data on.
