Service-oriented architecture (SOA) is set of designed principle that is basically used in developing phases of systems & integrating components while computing. SOS offers the complete pack of functionalities based interoperable services which are used specially with multiple systems under different business departments. SOA is not only used in business segment, but also for consumer services like enabling web-based applications. SOA has wide range of applications in the field computing especially in Security & Centralized data sharing management. XML is commonly used for interfacing with SOA services, though this is not required actually. SOA has lots of extensions in Web 2.0, Mashups, Digital Nervous System, and Software Development programs.
SOA works as integrating platform between the web based applications & multi-integrated systems. Instead of defining APIs & other parameters, it is designed on the interface of connecting different protocols & functionality. SOA functionally works as

SOA system is fully dependent on the mesh of software’s. All these services comprise of unassociated, loosely coupled units of functions. Under the action of first implementation, each service offers as filling out an online application for an account, or viewing an online bank account or booking air ticket etc. Within this system, aligned embedded calls pass through the source code, which are usually defined for description of metadata. Further applications are built by considering all these major sources. Underlying and enabling all of this requires metadata in sufficient detail to describe not only the characteristics of these services, but also the data that drives them. Analogously, the Web Services Description Language (WSDL) typically describes the services themselves, while the SOAP protocol describes the communications protocols.
