Research And Realization Of Defect-management System Based On EJB

Equipment-defect management is an important component of equipment management of power plant, and it is an important measure to ensure the level of health and security of power equipment, and it can also increase economic benefits.The article combination the transformation of management information system of Handan power plant, analyzes the current application status and problems of the de defect management system in the power palnt. In order to meet the needs of the defect management in the power plant, Firstly,this article analyses the requirement of defect management system, and then design the module of defects management, defects examination and defect statistics, defects query,then we introduce EJB middleware into defect management system,and put forward the development thought of the defect management system based on multi-tier structure of the middleware. Finally, we realize the defect management system based on EJB. The system has excellent scalability, maintainability and scalability.
