Since, right now we do not plan to go very deep into XML coding, we'll leave data definition here, and move future implication of XML.
Extensible Markup Language (XML), which complements HTML, promises to increase benefits that can be derived from wealth of information found today on IP networks around world. This is because XML provides a uniform method for describing and exchanging structured data. The ability to describe structured data in an open text-based format and deliver this data using standard HTTP protocol is significant for two reasons. XML will facilitate more precise declarations of content and more meaningful search results across multiple platforms. And once data is located it will enable a new generation of viewing and manipulating data.
Consider an industry where interchange of data is vital, such as banking. Banks use proprietary systems to track transactions internally, but if they use a common XML format over Web, then they'd be able to describe transaction information to another institution or an application (like Quicken or MS Money). Of course, they'd also be able to present data in a pretty Web page. FYI: This markup does exist. It's called OFEX, Open Financial Exchange format.
Under certain circumstances, if IE 4 on PC comes across a tag with proper contents, a function is started that gives a user opportunity to update installed software. If you're using Windows 98, it's possible that you've seen this process in action without knowing it was an XML application.
