Abstract

The primary objective of service-oriented architecture (soa) is to use information technology to address the key goals of business today: innovation, agility, and market value. Agility in soa is achieved by use of the principles of encapsulation, modularity, and loose coupling. Loose coupling enables customers to rapidly reuse services in new applications where strong consistency must be maintained to achieve the primary business objectives of the application. When applications are composed of loosely coupled services that are independent i.e. it is owned by different parts of the organization, based on disparate technology assumptions, and evolving on independent schedules and with diverse priorities, the consistency of the composite application can be undermined. This paper examines how consistency can be created and retained in loosely coupled applications. In this context, use of semantic ontology, a technique to achieve and maintain consistency of composite applications using soa is presented. Keywords: Service Oriented Architecture (soa), Agility, Coupling, Cohesion, semantics, Ontology, Web Ontology Language (OWL)
