Q10573286

Q10573286 refers to the programming language "XQuery". XQuery is a functional and statically-typed query and transformation language designed to query collections of XML data. It follows the syntax of XML and is similar to SQL in its capacity for querying databases and producing result sets. With XQuery, developers can extract and manipulate data from both simple and complex XML documents by using path expressions, functions, conditional statements, variables, modules, namespaces, typing constructs that promote reliability at compile time. Commonly used with the database standard XPath 2.0 or higher for use with Extensible Stylesheet Language Transformations (XSLT) 2.0 or higher engines that allow one to perform queries on disparate types of data sources including relational databases themselves as part of an ETL process within Data Warehousing environments or elsewhere.
