This book is designed to teach you the best practices in developing Windows DNA applications. We have avoided making this book a primer on every technology associated with Windows DNA. If we had followed this course, this would be an encyclopedia set. Everyone has their favorite authors and books on the various technical subject areas. The market is full of books to teach you the basics, the how, this book tries to be different in that we pull out the important points to teach you about the why. If you need training in a particular technology covered in this book, Sams has a number of 24-hour and 21-day books that cover a wide range of topics.

Never have telecommunications operations and network management been so important. Never has it been more important to move away from practices that date back to the very beginning of the telecommunications industry. Building and con- necting systems internally at low cost, on an as - needed basis, and adding software for supporting new networks and services without an overall architectural design will not be cost effective for the future. Defi ning operations and network manage- ment requirements at the 11th hour for new technologies, networks, and services deployments must also change.
