XQuery 3.1 is a versatile query and application development language, capable of processing the information content of diverse data sources including structured and semi-structured documents, relational databases and tree-bases databases. The XQuery language is designed to support powerful optimizations and pre-compilation leading to very efficient searches over large amounts of data, including over so-called XML-native databases that read and write XML but have an efficient internal storage.
