4.0 out of 5 stars
Presents a Terrific Case Study, November 5, 2000
Let me put my review in perspective. I have been programming in one language or another for twenty years. I was the project manager for a Fortune 500 company's e-commerce initiative. I do some consulting on the side. In other words, I consider myself to be an veteran programmer.This is not an introductory text. As with most Wrox "Professional" titles, Spencer presumes a certain level of experience on his reader's behalf. I find these titles to be exactly what I desire: not too simple to be trivial, and yet not as dry as a pure reference text. XML has been a hot topic for over a year now. As a result, more and more people are trying to get a grasp of this technology. Most of the XML books that I have read (and I own a few) provide reasonable explanations of it. I found that understanding the concepts of XML was simple; it was trying to figure out where to use it that was difficult. These beginning books told me the "how," but not the "when." "Professional XML Design and Implementation" fills this void nicely. The entire book is dedicated to explaining a realistic scenario from end to end. I will note that this book does focus entirely on Microsoft's implementation of XML, but this is a reasonable choice: even at the present time, IE 5.0 or greater is the only released browser that supports XML (I am not including Netscape 6 PR1 through 3 simply because they are still in beta). Along the way, Spencer provides us with a clear commentary as to why he made certain design decisions. He also attempts to include some instruction. Most of it is still accurate, but the section on XSL is now very outdated. The application itself is pretty creative. The code behind it is diverse: server side scripting is used to build XML from data stored in a database; client side scripting is used to build XML data within a browser without requiring round trips. One particularly interesting feature was to save the work done on the client side in a cookie so that it could persist between sessions, before finally being submitted to the server. I believe that most companies who are interested in XML at the time of this review are more interested in B2B (business to business) scenarios than B2C (business to consumer) ones. The limited browser support mentioned above makes this a reasonable assumption. The last chapter of the book entitled "The Transactional System" provdies some good insight into how XML can be used in a B2B environment. A small drawback is that the book does not contain (and therefore does not review) the entire code listing for this application. Thankfully the files are available on Wrox' Web site. This is a great book if you already have at least a cursory understanding of XML, and are looking to understand more about its application. If you are still struggling with the "what is XML?" question, then I recommend that you start with a different title than this one, especially when you consider that the XML/XSL standards have evolved considerably since its writing.
