Encoding requests and responses

Simple Object Access Control (SOAP) is a messaging framework for exchanging information between applications and web services. When SOAP is used, web service requests and responses are encoded in Extensible Markup Language (XML), a well-established text-based standard. XML elements and attributes identify the data that is exchanged between the web service and IBM® DataStage®. Using an XML schema, the web service stipulates which data is needed for the exchange.
