There is some good information in this book but for the most part it is far too simple. For instance, almost no attention is paid to the critical topic of validating user data. I've heard this should at the least be done on the server, and possibly on both the client machine (using Javascript) and the server.Again, no useful information is presented on the matter of preventing respondents from going back and changing data once they have entered it. These are a couple of issues that have been encountered by market researchers who have already managed a web survey or two.While this book cannot be all things to all readers, it does claim to be a handbook. Handbook means reference, and I expected these topics to be covered better.
