Open-source J2ee Architecture Educational Management Information System Design And Implementation

With the rapidly development of the information technology,the digitalization of the administration arise more and more recognition in every walk of the society.With the development of scale of education and the lack of educational resources,the job of the educational management department is more and more heavy.The education management system can make the work easyier and the database can make the work more standard.The essay studies the Education Management Information System of XiChang Normal University included the requirements of function of system,the requirements of performance of system,requirements of data operation of system.The essay studies the Education Management Information System based on the spirits of software engineer development.The key of the essay is the study about the J2EE architectures based on open source software.J2EE(Java 2 Platform Enterprise Edition) is a standard platform offered by Sun company for developing Web-based enterprise application,which give people rich technical choices.However,to build up a high-quality application depends on the support of well-designed J2EE infrastructures.So how to use these core J2EE technologics to design and build a stable,scalable and reusable infrastructure of Web application is still a problem the essay must focused.On the basis of the analysis and compare of outstanding J2EE technologies,the essay studies the serial J2EE architectures as well as the different developing models.With regarding to the popular framework:JSP+Servlet+JavaBean,Struts+EJB,Struts+Spring+Hibernate,the essay discussed their advantages.In course of the material system design,the J2EE architectures have been studied further.The mode of MVC has been used in the design of the the Education Management Information System.Moreover,the architecture of Webwork+Spring+Hibernate is a realization of the MVC mode.Through the reaserch of the architecture of Webwork+Spring+Hibernate,the merits are known that high efficiency of building up,predigesting data query and intuitionistic feedback.So the architechture has been used.The open source software is used priority in the design environment and the implement environment.The open source programme environment is intellij idea except for JDK.In the course of the study,a technology about database query has been mentioned for propose of simplification the code design and improving the efficiency of developing system.The chatacteristic of the information system are:the coupling degree is low enough to tolerate bugs based on the mode of MVC;the system is easy to transport to other operation systems;he system manages the expansibility,retractility and platform-irrelevant;the system is staticfied with the special demands of the education operation items;the rapid develop mode has been used in the course of developing in order to realize the functions.Finally,the interface is showed to indicate the part of the system.Through the test of system,the result has showed that the system has worked normally.
