The document discusses Yahoo Query Language (YQL), which allows users to query and combine data from hundreds of web services using an SQL-like language. YQL can be used to filter, tweak, and combine data across many APIs. It also provides tools to store data in the cloud, translate tweets to different languages, and make APIs accessible via YQL tables. YQL enables building applications faster by allowing developers to access and combine data from many sources through a simple query language.
