Trends in
Web services
Using
different standard protocols Web services help businesses to create
sophisticated applications that integrate many features and content.
Let us briefly discuss the uses of Web services now.
Web services(applications) can communicate which other without platform
hassles. A Web service developed in Java in a sun ONE environment
can communicate with the other which is running in a .NET environment.
Using the standards, its easy to make them communicate. If applications
can be integrated easily in this way, there are high possibilities
to minimize the integration cost. Unlike buying and installing COM
or Bean components Web services can run in the places where it is
since they are XML based.
Without developing new infrastructure companies can access other
Web services, and hence the development cost for newer applications
are totally reduced. Without changing the legacy code doing e-Business
can be made simple.
But there are risks at the other end. Unless the web service is
worth to buy and easy to integrate, companies may face tough time
to sell them. As the customers are not paying for the technology,
the integration part alone can not boost the sales. The market for
the commercial web services should be in needy areas. For example,
An online book selling company can create a stock Web service which
can be used its reseller applications.
The
participants?
Let
us now start discussing and understand the standards you need to
know before creating a web service. The new connectivity standards
SOAP, UDDI & WSDL and the matured standards XML and HTTP, web
services can be created, implemented and can interact with other
web services dynamically. Let us look ate the participants who make
web services here one by one briefly. The links can help you to
study them in depth.
XML
- The ideas behind Web services are starts
with XML. XML -- the eXtensible Markup
Language -- forms the backbone of the Web services
to create and implement. XML is a markup language like HTML. XML
has been designed to describe data and unlike HTML, XML tags are
not predefined in XML. XML is self-describing which uses a Document
Type Definition (DTD) to formally describe the data. XML was conceived
in 1996 by a team chaired by Jon Bosak. World Wide Web Consortium
(W3C) recommended XML for standard, during January 1998. XML has
been derived from Structured Generalized Markup Language (SGML)
parent and Hyper Text Markup Language (HTML) is said to be earlier
cousin of XML.

XML
is a world wide agreed standard, and almost all the technical giants
are into it. [Next Page]
