Detailed explanation-1: -Explanation : Service-Oriented Architecture helps to use applications as a service for other applications regardless the type of vendor, product or technology. Therefore, it is possible to exchange the data between applications of different vendors without additional programming or making changes to services.
Detailed explanation-2: -Service-oriented architecture integrates distributed, separately maintained and deployed software components. It is enabled by technologies and standards that facilitate components’ communication and cooperation over a network, especially over an IP network.
Detailed explanation-3: -a) Service Oriented Architecture (SOA) describes a standard method for requesting services from distributed components and managing the results. b) SOA provides the translation and management layer in an architecture that removes the barrier for a client obtaining desired services.
Detailed explanation-4: -A Web service is a “call” to an application, a system, or a hub that asks a question, like: “Does this customer already exist?” By definition, a Web service uses the web to communicate its business question. SOA, on the other hand, is the architectural framework that enables a series of those Web services to occur.
