The World Wide Web (WWW) is today an enormous market and it will continue to grow in the future as more and more people are being connected to it. This global market has attracted companies and Web publishers to create applications and Web pages in ever-larger numbers. This in turn has led to a growing development of standards and structures to assist their efforts. Prior to 1998, the exchange of data and documents was limited to proprietary or loosely defined document formats. But the advent of HyperText Markup Language (HTML) - the presentation markup language for displaying interactive data in a web browser - offered the enterprise a standard format for exchange with a focus on interactive visual content. However, HTML is rigidly defined and cannot support all enterprise data types, and those shortcomings provided the impetus to create the Extensible Markup Language (XML). The XML standard allows the enterprise to define its own markup languages with emphasis on specific tasks, such as electronic commerce, supply-chain integration, data management and publishing. The attention paid by the Internet community to Extensible Markup Language (XML) is impressive. XML has been heralded as the next important Internet technology, the next step following the HyperText Markup Language (HTML), and the natural and worthy companion to the Java programming language. This paper introduces the XML, as well as its benefits to the enterprise. Then it discusses the impact that it will have on the existing technologies such as Electronic Data Interchange (EDI) and the using of XML with Java Technology. It also makes a survey study of the associated industry specification and benefits from the users' side based on industry, country and vendors. The end of this paper will use statistic tool to discuss the survey result of using XML.
