Research And Development Of Oil Industry Equipment Management System

With the development of the information technology and the information system, it is more and more important for many enterprise database to promote its informationzation and enhance its management levels.Equipment management of oil industy is an important component of the oil industy enterprise management, the key to enhance the oil industy enterprise management level is to consult the advanced oil industy equipment management theory and oil industy enterprise management model home and abroad. At the same time, a sophisticated oil industy equipment management information system is not only a concernful method to solve the question of lacking of data and imperfect information sharing in some oil industy enterprise but also an effective step to regulate the business processes.The article includes the theory of equipment management, the equipment management information system, the vital question of system development and the design and realization of system.The J2EE platform is a system structure for the requirement of the enterprise application, and the simplification of the development and development for enterprise's solution, and the management of the relevant complicated problem. Its core is EJB. To the different constructing of the network enviroment of the equipment management system, we introduce EJB into equipment management, put forward the development thought of the equipment management system based on multi-tier structure of EJB, study the architecture and the technique on EJB deeply,provide the concrete system design, discuss EJB design mode, reduce the expenses of the long-range method call and transfer, improve the performance of the system, reduce systematic complexity. On the data tier, EJB tier, web tier, we have realized function such as user managing, recording and inquiring about the account book of the equipment, inquiring the state of the equipment,producing the equipment use calendars, adjusting equipment use calendar by hand, recording equipment use account of history, have a look around the arrangement of the equipment and producing various kinds of report forms. Finally, we build the system based on multi-tier structure of EJB, the whole design philosophy of the system and the design method are realized basically in the equipment management information system.
