XML:

(Extensible Markup Language): Designed especially for Web documents, XML is used to tag an

application’s code to specify the definition, transmission, validation, and interpretation of the tagged

data. To start an analogy, think of using XML to encode the message to be sent.

SOAP:

(Simple Object Access Protocol): This messaging protocol is used to encode the messages as

Web service requests and responses before they are sent across the network, most commonly via the

HTTP Protocol. A good way to think of SOAP is as the envelope for the message.

WSDL:

(Web Services Description Language): WSDL is an XML-formatted language that describes a

Web service as a collection of communication endpoints that can exchange messages, so that any

services that recognize those endpoints can communicate with each other. The WSDL specifies the

Delivery options available to the SOAP envelope. Salesforce is WSDL 1.1 compliant.

XML is used to tag data, SOAP transfers it, and the WSDL describes the available services

and their endpoint.

If you want weather some information, we will utilize services from the information provider.

Ex: In banking industry if they want to verify PANCARD, they will use Income Tax webservice or any other service provider who is having PAN card data.

Communication language between two systems:

1. XML (Extensible Markup Language)
2. JSON (Java Script Object Notation)
