Building distributed web applications is a wide-ranging topic, covering a variety of technologies and techniques. Windows DNA is the name given to the combination of traditional n-tier architecture with the intrinsic Windows 2000 services, including COM+, MSMQ, and Active Directory. Using this architecture, you can design and build scalable enterprise-level distributed applications on the Windows 2000 platform.

This book takes an in-depth look at the DNA architecture, focusing on fitting the pieces of the puzzle together. Each of the logical tiers is examined, with particular emphasis placed on the features COM+ contains to make component building simpler and more powerful.

Who Is This Book For?

This book is for anyone involved with building distributed web applications that want to see the bigger picture. As such the book assumes a working knowledge of VB and ASP in places, but the emphasis is not so much on the code as on where each of the pieces fit into the puzzle. I t' s designed to give you an idea of how each area or technology affects you, enabling you to make informed decisions about whether to pursue a subject further, or confidently assert that you can do without it.
