Current business climate demands a high rate of change with which Enterprise Information Systems Integration is required to cope. Previously isolated, these systems must be converted to service-enabled architectures and integrated efficiently to gear towards the real world of fully automated, complex electronic transactions. Service-Oriented Computing (SOC) holds the visionary promise of a world of cooperating services where application services are encapsulated within old and new applications. This paper presents SmartWorld, a service-oriented architecture (SOA) which attempts to enable integration among Enterprise Information Systems using services as the basic constructs to support the development of rapid, lowcost and easy modeling of Business Process interoperation.
