????????????????????￡?What is SOA?
????In recent years?? outsourcing and advanced business needs required companies to collaborate and share information. In addition?? with the rising number of mergers and acquisitions?? businesses struggled to find a way to share data. If?? prior to a merger?? two businesses maintained their own proprietary computer systems?? after the merger?? the sharing of data could be very time consuming and costly.For these issues?? several vendors developed technologies to handle B2B (Business-to-Business) communication. Examples of B2B technologies are RMI?? COM?? CORBA?? EDI?? and Web services. In addition to allowing the systems to link up to one other?? the technologies also handle permissions to allow networking with each other like an Intranet.
????SOA systems are primarily based on Web services. In Web services?? a client submits a request and the Web server provides a response using the SOAP protocol. HP Unified Functional Testing for API testing lets you check the behavior of your Web services in an automated manner.

????HTTP??Hypertext Transfer Protocol?? a communications protocol used to transfer or provide information overthe World Wide Web. Users utilize HTTP to publish and retrieve HTML pages.
????JMS??Java Message Service?? a Java-based Message Oriented Middleware API for sending messages between two or more clients.
????REST??Representational State Transfer. A style of software architecture for distributed systems.
????SOAP??Simple Object Access Protocol?? or Service Oriented Architecture Protocol?? a protocol for exchanging structured and typed information between peers in a distributed environment using XML sent over HTTP or JMS. SOAP lets you serialize distributed components into XML documents for transport and deserialize them upon reaching their destination. This promotes
????interoperability between components that are based on different technologies.
????UDDI??Universal Description?? Discovery and Integration?? a platform-independent?? online registry listing businesses worldwide. It is often used as a database for public Web services.
????Web Services??Standardized?? Web-based applications using the XML??SOAP?? WSDL and UDDI standards over an Internet protocol. XML is used to tag the data?? SOAP is used to transfer the data?? WSDLs describe the services and UDDIs list them.
????WSDL??Web services Description Language?? an XML-based language designed to describe a Web service. The WSDL document provides essential information about the Web service??such as its ports and operations??required for implementation.
????WS-I??Web Service Interoperability?? a standard created by the Web Service Interoperability organization to promote compatibility between Web Services.
????XML??Extensible Markup Language is a general-purpose markup language. It is called extensible because it lets you define your own tags. It enables the sharing of structured data across different information systems??especially over the Internet. XML is used both to serialize data and encode documents.
