Integrated Supply Enterprise Soa-based Operation Support System Realization

Enterprises want to achieve the core competencies in the increasingly keen marketable competition,so that access to greater benefits and improve the level of corporate information will be an important means of instruction.At the present stage, the enterprise has built a large number of applications,the systems in their respective business areas play an important role,but they often independent of each other and cannot work together well,resulting in the formation of a lot of information silos within the enterprise.At another side,the modern enterprise faced with enormous market pressures competing in the fierce market situation.If enterprises want to adapt to changing market needs and business processes of rapid change,they must have a flexible and agile information systems.Insuch circumstances,the Service-Oriented Architecture(SOA)came into being.In order to solve the problems of reuse and integration in electric power enterprise informatization, it is suggested that SOA (Service Oriented Architecture) should be applied in power supply enterprise Operation Support System to realize function reuse and data sharing. This paper proposes a power supply enterprise OSS (Operation Support System) model based on SOA, which includes an information integration platform, an enterprise portal and a series of business application systems. Information integration platform is used to realize EAI (Enterprise Application Integration), it uses ESB (Enterprise Service Bus) as a hub to connect service requester and service provider to avoid a point-to-point integration. Business function provided by application systems are realized by using Web Services and these Web Services will also be published on the information integration platform to realize function reuse. EP (Enterprise Portal) shows service and data of information integration platform, EP based on SOA is different from traditional EP, it is loosely coupled. The function of user interface can be reused, combined and trimmed.Test results show that the power supply enterprise OSS model can integrate business application systems. Various application systems handle business and share data as a whole. The model eliminated the information island. This fully proves that the best applications of Web Services are software reuse and EAI.
