An
overview of soap and how XML is used in it
SOAP is
a protocol for communication between different machines that might work
in different environment. It was derived from XML RPC standard and is
moving towards ebXML.

With
SOAP you can invoke methods that are available in objects available
in remote machines. SOAP uses XML for the method calls to be invoked.
The data for invoking the remote object's method is sent via the HTTP
using XML. SOAP can be implemented as server or client.
Base level
encodings are used to define the type of data that can be used. It could
be a simple one or a complex one. When we say simple values it could
be integer, float, and strings. The complex types could be arrays, structures,
and other complex types that are defined in the XML Schema group. Rules
for object serialization are also defined in the encodings.
In short
we can say that SOAP is a communication framework that is used by the
clients and the servers to invoke the remote methods in objects found
in remote machines using XML data. It is a messaging oriented protocol.
