XML is an enabling technology As an omnimorphic data format, it will encourage interoperability However, as it becomes more pervasive, XML will virtually disappear from the media If it is everywhere, it will be like an ocean to a fish, unseen This has already begun to happen with B2B e-commerce The first major articles in February and March 2000 about the B2B collaboration among the big automakers never even hinted at XML The Wall Street Journal, the Dallas Morning News, and the Washington Post were all silent about XML A few weeks later, though, a tidbit about XML began to surface The enabling technology is not news The business and the billions make the headlines And that is the way that it should be Business drives technology and technology enables business But a good businessperson needs to be aware of emerging trends and how they might impact the business

The technology that XML represents is similar to that of the transistor Except for electronic engineers, no one cares about the lonely transistor Just after the vacuum tube, companies used to brag about how many transistors were in their radios Then integrated circuits were invented and microprocessors with millions of transistors The number of transistors in a Pentium III is no longer common knowledge Intel will be more than happy to reveal this information, but no one wants to listen, except for competitors Consumers are now interested in processing speed The same thing will happen to XML as happened to transistors In fact, it is almost there The news about B2B greatly outweighed the underlying XML technology More articles exist about B2B or about wireless data access than about XML But XML is the foundation of these technologies A general understanding about XML helps in understanding more about these technologies and what their business potential could bring Although XML will not bring in the money, the applications that are developed using XML will From B2B to WML to holographic processing in the more distant future; these applications are the ones that will bring in the profits With XML applications, the Web has the potential to become a worldwide data warehouse with connectivity to a wide variety of devices Each application has its own separate potential to make money A businessperson should maintain awareness of emerging technologies To paraphrase Bill Gates, how will a user react when information is free Each manager can answer that question in the way that is most profitable to the specific organization

Schemas and Document Type Definitions (DTDs) form the meta-data that enables an XML document to be self-describing Although they have very different constructs, schemas and DTDs serve the same general purpose: to define the rules and data elements within an XML document They attach context to XML documents that can be read by humans and by machines The specific flavor of XML syntax that a given DTD or schema defines is called a vocabulary The vocabulary may cover a set of XML documents or only one document Although DTDs are the more mature technology, the World Wide Web Consortium (W3C) is pushing the specification and acceptance of schemas Each construct has advantages, but advocates believe that schemas provide the superior extensibility and compatibility with the XML format

Schema may be an unfortunate choice of terms because database theory also uses the term schema In fact, the word schema is used in different modeling disciplines and means something different in each context An XML schema has no relationship to a database schema An XML schema is a construct used to represent the data elements, attributes, and their relationships
