ACHIEVING RELIABILITY OBJECTIVES WITH THE AID OF A SERVICE ORIENTED ARCHITECTURE

摘要

This paper describes why and how a Service Oriented Architecture (SOA) is being implemented by California ISO to realize its business processes. After a brief overview of the program scope, a general description is given of the process being used in the program to specify how business requirements - such as those for reliability - are modeled and then orchestrated in the SOA. This includes articulating the sequence and contents of information exchanged among disparate applications across organizations. To support each exchange, services are defined in Web Services Description Language (WSDL) whereby the abstract service definition is automatically built from California ISO's semantic data model, which is an extension of the utility industry's Common Information Model (CIM).
