What are the web services?
Web Services is a web application. And it communicates using open protocols.
The web services expose methods that can be use by another application can use.
Using Web services your application can publish its function or message to the rest of the world.
Web services use XML to code and decode your data and SOAP to transport it using open protocols.
The basic Web services platform is XML + HTTP,
HTTP is the very common Internet protocol.
The XML provides the web services can be used between platforms.
Comment:
Web Services have three basic platform elements.
These are called SOAP, WSDL and UDDI.
• SOAP stands for Simple Object Access Protocol
• 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 based on XML
• SOAP is simple and extensible
• SOAP allows you to get around firewalls
• SOAP will be developed as a W3C standard
What is WSDL?
WSDL is an XML-based language for describing Web services and how to access them.
• WSDL stands for Web Services Description Language
• WSDL is written in XML
• WSDL is an XML document
• WSDL is used to describe Web services
• WSDL is also used to locate Web services
• WSDL is not yet a W3C standard
What is UDDI?
UDDI is a directory service where businesses can register and search for Web services.
• UDDI stands for Universal Description, Discovery and Integration
• UDDI is a directory for storing information about web services
• UDDI is a directory of web service interfaces described by WSDL
• UDDI communicates via SOAP
• UDDI is built into the Microsoft .NET platform

What are the Web services can do?
The Web Services enable the client side using the Web Services remote methods. And it also provides the developer a good opportunity to use SOAP without expert knowledge of its implementation. The web services support the user using many kind of data type, such as intrinsic SOAP data types, arrays, objects, and XML data. So web services help solve the interoperability problem by giving different applications a way to link their data.
