Application And Research Of EJB Distributed Component Technology For System Of Distributing Oilfield Data

In this paper, it is firstly introduced the subject background of academic and business, then explains about the reason of choosing EJB technology in comparison to the difference of three mainstream distributed component technology currently and explored EJB technology deeply. Base on the above research, it is designed and developed the system of distributing oil well performance data based on Web technology and realized the increase of EJB performance by use of design pattern. Distributed component technology just is the best choice which is used for developing large-sized Web enterprise application and it has good behavior in bumping up processing ability, system collaboration ability, expansibility and safety property. Using EJB distributed component technology in system of distributing oil-field data is an effective pathway for accomplishing"information petroleum".The system of distributing oil well performance data based on Web technology has been put into commission which has been running steady from the present situation. The system has flavors that are high expansibility, good flexibility and strong maintainability. The design pattern and technology used in development of the system are effective methods which can bump up EJB performance.
