Jsp, Javabeans And Servlet-based Academic System, Research And Development

On February 10, 2004 the Ministry of Education "2003-2007 Year Education Promotion Planning for Action " proposed explicitly the implementation "The Education Informationization Construction Project", simultaneously Information Engineer College Of Henan also proposed three years realize "The Digitized Campus" project. Under this background, this article carried on application of education administration business in Information Engineer College Of Henan, a research analysis to the MVC of J2EE development mode, JSP+JavaBean+Servlet technique, three layers of system structures and the applied technique of the Tomcat 4.1.36 under the red flag Linux operating system. On this foundation, carried on a detailed system demand analysis and the system design to The Educational Administration System.The Educational Administration System of this article have designed on the basis of in-depth studying the MVC development model of J2EE and learning JSP +JavaBean + Servlet technologies. In the J2EE developing pattern of MVC, the M represented of model, that is, data structure. In the data services and background respect, using SQL Server 2000 database, the systems have planned a scientific and rational data structure in accordance with my familiar education business system of process management. V represents of the data of the presentation layer, that is, data showing, that data showing use combination of JSP pages and Servlet pages, Servlet can better hide the real procedure document, which provides a security for the system. C represented data control or named data processing. It used JavaBean technology for data processing, which facilitate the realization of data-processing business processes, but also better protect the data-processing procedures statement and add a security barrier for the system.In the Environmental of The Educational Administration System operation aspects, it spent me much time to take an in-depth study of the application of the Linux operating system and the structures operating system environment. The system focuses on applications of the operating Tomcat 4.1.36 under the Red Flag Linux system that developed by the Chinese Academy of Sciences. The Linux system operating stability, and it also is open-source operating system. The system provides convenient for the safety of the operating system itself, at the same time Linux operating system expressed its better superiority for virus resistance and the provision of network services.In the system architecture aspects, selected a safe and reliable system architecture on the basis of studying the focus architecture which be used currently. Through there search, the contrast, the analysis, this system movement plans three overhead constructions, the system entire movement overhead construction divides into three parts: client, application server, database server. These three parts on the network overhead construction, the client and the application server end belong to the identical network. The application server and the database server simultaneously are in other network, which like this realized the user and the database isolation, avoided the user jumping the application procedure direct revision database risk, this has guaranteed that if the user wanted change the data it have to use the application procedure, this has provided the safeguard for the system safe operation, increased the security, the consistency of the data.
