Research And Implementation Of The Automobile Cooperative After-Service System Based On NHibernate And ORM

At present, the automobile industry is one of the fastest-developing and most competitive sectors. With China's entry into the WTO, foreign automobile manufacturers to enter the Chinese market strong, which intensified the competition in the domestic automotive industry. In the fierce competition directed by technology, the gap in the function and the quality of the automotive products has been getting smaller and smaller. In order to put them in an invincible position, car manufacturers tried to make change from the after-sales service.Currently, after-sales service in most of the small and medium-sized domestic car manufacturers is still in the traditional mode of information exchange. An increasing number of the car manufacturing companies have been unable to adapt to the fierce competition in the automobile industry. Therefore, the establishment of after-sales service information system which is in order to improve service levels and the reduction of costs could be the reliable guarantee for automobile enterprise to enhance their competitiveness.This article first analyzes the present status and the problem of the domestic automobile after-sales service management, contraposing to the status of capital deficient and technical weakness in small and medium-sized automobile enterprise, then bring forward the solution of setting up the automobile after-sales service system which is based on the ASP (application service provider) of automobile industry chain platform. On this basis, this paper analysis the business processes of automobile collaborative after-sales service system in detail and researches three types enterprises of services,manufacturers,suppliers in the collaboration of collaborative after-sales service processing.Then it adopts the NHibernate and ORM technology in the design to build the N-tier architecture which is based on NHibernate. By designing the NHibernate persistence layer and the scheme of ORM in system, the automobile collaborative after-sales service systems would be implemented basing on NHibernate and ORM's N-tier structure. The realization of the NHibernate system persistence layer has been mostly focused. Finally, some available proposals have been raised to optimize the system through the use of NHibernate's with excellent performance.
