"Microsoft Mastering: Ecommerce Development" provides practical, hands-on instruction for creating Web-based commerce applications using Microsoft's Site Server 3.0 Commerce Edition and pipeline technologies. More than a tutorial, the Microsoft Mastering learning system features a variety of tools and building blocks to help developers create working solutions. Instructional modules -- available both in print and online -- step learners through each part of the development process and explain how to add or extend functionality. Students then apply their new knowledge and skills through guided lab exercises. By the end of the course, they've created a simple e-commerce site and basic order-processing pipelines. With its combination of text-based instruction, interactive lessons, narrated demos, hands-on labs, and reusable code, Microsoft Mastering Ecommerce Development delivers the training developers need -- how and when they need it.
