Design And Implementation Of The Enterprise Information System Based On J2EE Technology

The development of science and technology especially the computer technology,network and communication technology makes the cost of Enterprise Informatizationdown continually. More and more enterprises begin to make much account of theestablishment of informatization. Without informatization, the enterprise’sconstant,standardized administraton and promotion of key competitiveness is nothingness.Because of inadequate fund and lack of excellent management, those small andmedium-sized developing enterprises frequently can not give a over-all planning duringtheir informatization establishment process. It leads to that the disposition environmentand running environment of various information systems are different from each other.In this case, which result in the various subsystems of the enterprise informationmanagement to heterogeneous databases interoperation and then make the enterprise runinto the problems of "Information Isolated Island". In order to resolve these problems,this paper based on J2EE and SOA is to study the real estate enterprise officeautomation system from the following respects.On the aspect of this article’s structure, it firstly introduces enterprise’s status quoof working flow and background of the information platform management system，andthen introduces the characteristics of The J2EE technology, lightweight J2EEframework and the SQL Server database. After that analyzes the requirement of thefunctions and targets.on the base of requirement, it describes the system’s designingmethod, the total designing project and the specific realization way of thissystem.then,it introduce the operation of the system, the system functionality andperformance testing and analysis. Finally, it puts forward some deficiencies of thesystem and the recommended improvement methods，and does overall comprehensiveconclusion of this paper.The research of the enterprises information system based on J2EE can not onlymeet the real estate business daily office basic needs, but also the data communicationbetween heterogeneous systemsis achieved by using the Web technique.So we cansolve the problem of isolated islands of information in enterprises and achieve the goalof office automation in real meaning.
