XQuery is a query language designed for querying XML data. It allows for the extraction, manipulation, and transformation of XML documents, enabling users to retrieve specific data elements and perform operations such as filtering, sorting, and joining.

An XQuery expert must have strong proficiency in XML and related technologies such as XPath and XSLT. They should understand schema definitions (XSD), be adept at writing complex XQuery expressions, and possess knowledge of XML databases and data integration techniques. Familiarity with programming languages like Java or Python for integration purposes is also beneficial.

How to hire a Xquery expert

XQuery was developed in the early 2000s by the World Wide Web Consortium (W3C) to address the need for a robust query language for XML data. It became a W3C recommendation in 2007, providing a standardized way to query and manipulate XML documents across different systems and applications.

About Xquery

Strengths of XQuery include its powerful querying capabilities, ability to handle complex XML data structures, and integration with other XML technologies. Weaknesses include its steep learning curve and limited support outside XML-centric environments. Competitors include SQL for relational databases, JSONiq for JSON data, and SPARQL for RDF data.
