YQL (Yahoo! Query Language) is an expressive SQL-like language that lets you query, filter, and join data from Yahoo!, Facebook, Google, Twitter, and a variety of other Web services. With YQL, you can read, write, and shape data across the Internet (in both XML and JSON formats) through simple REST requests, eliminating the need to learn how to use different APIs.
