Components of Web Services by R4R Team

Components of Web Services:-
There are several component of Web Services as follows;

This is the simplest XML based protocol for exchanging information between computers.

 XML-RPC is a simple protocol that uses XML messages to perform RPCs.
 Requests are encoded in XML and sent via HTTP POST.
 XML responses are embedded in the body of the HTTP response.
 XML-RPC is platform-independent.
 XML-RPC allows diverse applications to communicate.
 A Java client can speak XML-RPC to a Perl server.
 XML-RPC is the easiest way to get started with web services.

SOAP is an XML-based protocol for exchanging information between computers.

SOAP is a communication protocol
SOAP is for communication between applications
SOAP is a format for sending messages
SOAP is designed to communicate via Internet
SOAP is platform independent
SOAP is language independent
SOAP is simple and extensible
SOAP allows you to get around firewalls
SOAP will be developed as a W3C standard

WSDL is an XML-based language for describing Web services and how to access them.

WSDL stands for Web Services Description Language
WSDL is an XML based protocol for information exchange in decentralized and distributed environments.
WSDL is the standard format for describing a web service.
WSDL definition describes how to access a web service and what operations it will perform.
WSDL is a language for describing how to interface with XML-based services.
WSDL is an integral part of UDDI, an XML-based worldwide business registry.
WSDL is the language that UDDI uses.
WSDL was developed jointly by Microsoft and IBM.

UDDI is an XML-based standard for describing, publishing, and finding Web services.

UDDI stands for Universal Description, Discovery and Integration.
UDDI is a specification for a distributed registry of Web services.
UDDI is platform independent, open framework.
UDDI can communicate via SOAP, CORBA, Java RMI Protocol.
UDDI uses WSDL to describe interfaces to web services.
UDDI is seen with SOAP and WSDL as one of the three foundation standards of web services.
UDDI is an open industry initiative enabling businesses to discover each other and define how they interact over the Internet.
