Web Services Let Companies
Link new and legacy systems to new applications
Conduct online transactions with less integration cost
Reduce time to market by decreasing development and testing time
Continually adapt applications to match new business processes
Web services can speed application development and reduce costs to access data on disparate systems.
Dissimilar legacy systems can communicate without expensive translation applications.
Developers don't have to know anything about systems they're communicating with.
Users only have to install a translation process for their disparate systems once.
Lack of agreement on a definition means confusion for users.
Standards are in flux, with more than a dozen competing schemes.
Services written to one standard will not work with Web sites supporting others without a translation service between.
Today, services created for one vendor's scheme won't necessarily work with another's standard (such as J2EE and .NET).
SOAP Simple Object Access Protocol allows information in XML to be exchanged and defines how applications execute Web services.
UDDI Universal Description, Discovery and Integration service helps applications find Web services elsewhere on the Internet.
WSDL Web Services Description Language lets Web services describe what they are, where they can be found and how they should be used.
