I also moderate the SCWCD forum. In the objects for the exam, 4 patterns are listed specifically. Value Objects, MVC, Data Access Object and Business Delegate. Are these discussed in your book? Could you give a a quick discussion of the potential benefits of each?

I Hope This Helps

I'll make a quick response to this now and come back later to add more. First of all, none of these patterns are discussed in our book. MVC (Model-View-Controller) is actually what is known as an architectural pattern. It is useful, but I now tend to agree with Alan Holub that it does not scale to the application level. The best description of MVC is in Pattern Oriented Software Architecture, vol 1. See Alan Holub's articles from our web-site at http://www.netobjectives.com/cop_java.htm See Object-Oriented Systems Part 1 about half way down the page.
