Windows DNA (Distributed Internet Architecture) forms the cornerstone for building scalable robust Web Applications using Microsoft technologies. The technologies within Windows DNA cover both the user's machines (clients) and the machines serving up the data from the Web (servers). It is thus Microsoft's "client-server architecture" for the era of the Internet, addressing the full spectrum of enterprise application development. This is the first book designed to help Windows developers decide not only which technologies to use, but also how to use them. It teaches developers to combine the wide variety of technologies that make up Windows DNA into effective solutions for their own enterprise application requirements. This book describes "best practices" that apply to building Windows DNA applications. These in turn derive from the author's long consulting experience in the client server world.
