Re: What are web services ?
>> Has the ability to perform its functionality synchronously or asynchronously To explain synchronous and asynchronous communication, I use a telephone example. If someone answers when you call, that synchronous. If no one answers but you leave voicemail, that's asynchronous. SOAP supports synchronous and asynchronous messaging. Using RPC-style messaging, communication is synchronous and the service provider and consumer maintain state. Document-style SOAP messaging (XML document in the payload) supports asynchronous messaging because you can encapsulate state information in a document. ======== Ken North =========== www.WebServicesSummit.com www.SQLSummit.com www.GridSummit.com
