Design And Implement Of Electric Market Technology Support System Based On J2EE

Currently in the our country, break the monopolization, build up the electric market mechanism that unify, open, compete, sequence, have already become inevitable trend of the electric industry development. The electric market technology support system is technique guarantee of the electric market, having the extremely important meaning to carry through of the assurance electric market "open public fair" principle and the electric market rule implement. Electric market technique the support system of the existing northeast region faces the market of the vehemence competition and customers fast and accurate request, need to be lifted the high performance up in the software design.Along with the technical fierce development of the computer science, the applied complexity of enterprise raises continuously, the enterprise software system structure also appears such as various applied terraces of J2EE .net etc... Because of open environment, perfect system structure and other development environments that it open not the huge advantage, J2EE (the Java2 Enterprise Edition) have got the approbation of the programmer. The existing frame of J2EE uses the most extensive in actual application develop of is a structure of Struts.The concept of the pattern had put forward in the application of 70's in 20 centuries to city and building by the Christopher Alexander first. In the computer realm, pattern also constantly was applied to each aspect of the software engineering. Such as the development organize, software processing, the item installs to manage etc. in many ways, can see the shadow of the pattern.This thesis designed an electric market technology support system that takes the J2EE system structure as the foundation frame, takes the pattern of various forerunner as to design the principle. Combine with the pattern of DAO and the factory pattern, quote from the EJB to complete the system to adjust to use to the backstage database...
