Abstract: Web Services constitute a distributed computer architecture made up of many different computers trying to communicate over the network to form one system. They consist of a set of standards that allow developers to implement distributed applications – using radically different tools provided by many different vendors – to create applications that use a combination of software modules called from systems in disparate departments or from other companies. The various services and protocols that make web services possible are as follows:SOAP (Simple Object Access Protocol) UDDI (Universal Description, Discovery and Integration) WSDL (Web Services Description Language) Other related protocols are: WSFL (Web Services Flow Language) ebXML (e-business XML) WebOS: web-services-architecture
