This is primarily a book about constructing an ASP.NET web site using stored procedures, and less a book about e-commerce. There are a few sections, mostly at the end, which are specific to e-commerce. These include the order processing pipeline chapter and the credit card transactions chapter.This is not to say the book is bad. It's very well written and the code is described step-by-step in detail. There could have been more emphasis on architecture, and a little more on e-commerce. I would also like to see some emphasis on the sticky legal issues like customer data management, password security, transaction security, and how and when to migrate the data off of the machines on the open Internet and back into safe storage on the Intranet.
