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

The XML is considered as the very special language which is capable to label the information content. The data from the structured and semi structured documents can be labeled in this way. The query languages are capable to display the intelligent use of these XML comfortably. In this way the queries can be employed across all sorts of data. The data which are physically stored in XML and stores as XML can be utilized in this way. The language which satisfies these specifications is generally known as XQuery languages. Thus these Query languages

Basics Active XML relies on two key notions: * AXML documents, that contain calls to web services, and * AXML services, that are declaratively defined as XQuery queries over AXML documents. They are used in a peer-to-peer architecture, where each AXML peer holds a repository of AXML documents and provides some AXML services. AXML documents Here is a sample AXML document: <directory> <dep name="Toy"> <sc>toy.xyz.com/GetToyPersonel()</sc> </dep> <dep

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
