YQL (Yahoo Query Language) allows users to query and combine data from different online sources. It enables applications to extract structured data from various formats, including JSON, XML, CSV, and HTML. Some key things YQL can do include scraping web pages to extract data, performing content analysis, and accessing real-time data from services like Flickr, Twitter, iTunes, and more. Developers can also create their own custom tables and functions with YQL.
