Amazon.com AWS 4.0 Web Services

It's out! And the new REST format makes quering the database extremely easy. Unlike the SOAP interface, REST allows you to get information from Amazon simply using a URL (with GET no less).

Amazon Web Services (AWS) is a method for programmers to access Amazon's massive database of books, software, music, etc. and their corresponding prices and reviews. You can even use it to post products (such as books). And the best part? It's free! All you need to do is sign up for an AWS account.

To the REST of the story (ok, ok, I couldn't resist). REST stands for Representational State Transfer and was developed by Dr. Roy Fielding.

REST allows you to make calls to AWS by passing parameter keys and values in a URL (Uniform Resource Locator). AWS returns its response in XML (Extensible Markup Language) format. You can experiment with AWS requests and responses using nothing more than a Web browser that is capable of displaying XML documents. Simply enter the REST URL into the browser's address bar, and the browser displays the raw XML response.
