W3C recommended on January,23 2007 status to Xquery the SQL did query language for relational databases , xml used the same language which was done by SQL, x query helps the user to work on one common model though it might be any kind of the work the user does. SQL/XML is different type of standard which uses declarative and portable queries return to XML by querying relational data, many might think why standard for XML and databases? The applications of the enterprise access and work with data from multiple desperate sources, from the

On Jan. 23, 2007 the W3C granted Recommendation status to XQuery, the XML query language designed to do for Web services what SQL did for relational databases. XQuery allows you to work in one common model no matter what type of data you're working with -- relational, XML or object data. It's used for queries that must represent results as XML, to query XML stored inside or outside the database, or to span relational and XML sources. SQL/XML is another standard that uses declarative, portable queries to return XML by querying relational data. It's an

XML is a versatile markup language, capable of labeling the information content of diverse data sources including structured and semi-structured documents, relational databases, and object repositories. A query language that uses the structure of XML intelligently can express queries across all these kinds of data, whether physically stored in XML or viewed as XML via middleware. This specification describes a query language called XQuery, which is designed to be broadly applicable across many types of XML data sources. This document has been

Abstract Mapping XML Schemas to class definitions and relational schemas allows for seamless marshaling and unmarshaling of an object's state to and from XML documents. W3C XML Schemas provide a rich set of datatypes and validity rules, both built-in, and user definable. It is possible to map data structures defined in a Schema document to data structures in object oriented languages and relational databases. This paper presents approaches to automating such mapping. In simple cases, a Schema document can be generated based on a class definition,

Emerging XML technologies are available in the following categories on alphaWorks: * Database - XML opens the door to a new generation of databases: object databases that can manage heterogeneous, non-tabular information. Relational databases manage a subset of XML, but XML is more general. * DTDs - The XML Document Type Definition (DTD) defines the constraints on a specific class of XML documents. It is used by the XML parser to validate and interpret individual XML documents. * Editors - XML is optimized for creating, editing, and viewing

Simplify XML Publising applications with Stylus Studio XML Publisher, a powerful XML report designer that allows users to create advanced document layouts for use in single-source publishing, XML content management, and multi-channel publishing applications. Using an intuitive visual interface, business users can easily design rich document layouts to publish XML content to PDF, HTML, Postscript and many other document formats using XSLT 1.0, XSLT 2.0, or XQuery 1.0. Stylus Studio XML Publisher supports numerous heterogeneous data sources including

Abstract : XML is an extremely versatile markup language, capable of labeling the information content of diverse data sources including structured and semi-structured documents, relational databases, and object repositories. A query language of similar versatility is needed to realize the potential of XML as a universal medium for data interchange. Most existing proposals for XML query languages are robust for particular types of data sources but weak for other types. In this paper, the authors combine features from several sources to propose a new

XQuery is a query language (with some programming language features) that is designed to query collections of XML data. It is semantically similar to SQL. XQuery 1.0 was developed by the XML Query working group of the W3C. The work was closely coordinated with the development of XSLT 2.0 by the XSL Working Group; the two groups shared responsibility for XPath 2.0, which is a subset of XQuery 1.0. XQuery 1.0 became a W3C Recommendation on January 23, 2007. "The mission of the XML Query project is to provide flexible query facilities to extract data
