A Web service is a discrete unit of code that handles a limited set of tasks. Although Web services remain independent of each other, they can loosely link themselves into a collaborating group that performs a particular task.
Microsoft .NET Developer is one such web service pack that provides a universal data format and allowss data to be easily adapted or transformed revolutionising how applications talk to other applications or how computers talk to other computers. Web services can communicate across platforms and operating systems, regardless of the programming language in which the applications are written.
They are semantically encapsulating discrete functionalities, wrapped in and accessible via standard Internet communication protocols like XML and SOAP that help the businesses work more efficiently with its partners and suppliers by simplifying communication processes. They unlock information so it can flow to every employee who needs it and reduce development time and expense for new projects.
.NET Developer application also make it possible for developers to choose between building all pieces of their applications, or using Web services created by others. This means that an individual company doesn't have to supply every piece for a complete solution. The ability to expose (announce and offer) one?s own Web services creates new revenue streams for a company.
