Addressing and Querying

PCMag.com offers an apt definition of XML: ‘an open standard for describing data from the W3C’, or the World Wide Web Consortium. One concept of XML that is really favourable to humans is the XML Addressing and Querying.

Hurrah! ‘Quality Magazines’ have a website I can change my address on. Isn’t modern technology wonderful?

To query XML proves to be highly advantageous. Queries on XML documents make the relational data generalized in an organized and straightforward way.

Through querying of XML documents, XML is able to generalize relational databases, and thus, these databases are in turn being made to support XML. Querying is done in XML through XQuery, a very powerful tool. Through XQuery, any XML document can be faithfully represented.

XML is made more useful through querying, as it provides solutions to some basic database problems, such as data extraction, conversation, transformation, integration, and others. Additionally, querying in XML is much favoured because of its simplicity and ability to support both possible views, ordered and unordered, on an XML document.
