摘要：Service oriented architecture (SOA) is a form of software design in which application component supply services to other components through a network communication protocol, it has many services that can transfer small data with communication channels or additional services which bring into a relationship that ensure efficiency of service activities, SOA simplify the structure of loosely coupled applicable applications and enable contribution for enterprise working of services together. In order to assure the effectiveness of Service oriented architecture we have to confirm service composition which is the collection of services together in order to perform a specific function which can be used in service oriented architecture. In this paper we proposed a Service composition in SOA, it is present service composition with various techniques used for composing services and provided a comparison between them.
