Research And Realization Of Electric Switching Order System Based On EJB Component Technology

Electric Switching Order System is mainly a two-layer structure,or the traditional three-layer structure,and can not satisfy the enterprises' demand,such as distribution, scalability and heterogeneity.J2EE(Java 2 Platform Enterprise Edition) is a choice of building the enterprise application,and EJB is the most popular technical specification. EJB component technology is studied in this article.On the basis of the theory,we set up the Electric Switching Order System based on EJB component technology,for power plant.Database structure and business logic structure are also designed.Finally,maturity and practicability of EJB technology are validated by realization of data storage layer and EJB layer.The system must be significant in power information construction.
