A guide to the fundamentals of ColdFusion MX 7 provides information on such topics as creating data-driven pages, implementing security mechanisms, building reusable fuctions, and interacting with Macromedia Flash.
This is an excellent guide to ColdFusion. I used it to teach myslef Coldfusion in order to interview for a programming job. I did not get the job, but I now have ColdFusion added to my list of programming skills.
This is a great reference book. I'm not CF expert so I can't review it in depth but what I can tell you is that it has helped me a lot when I have to start a project and I haven't seen a CF code in 6-months. For me it's a nice refresher book.
