J2ee - Education Management Information System-based Research And Design

J2EE (Java 2 Platform Enterprise Edition) is a standard platform for developing Web-based enterprise application, which give us rich technical choices. However, to buildup a high-quality application depends on the support of well-designed J2EE infrastructures. So how to use these core J2EE technologies to design and build a stable, scalable and reusable infrastructure of Web application is still a challenge we must face as well as an area on which this thesis focused.As one of the most concerned J2EE technologies, EJB specification updated its version to 3.0, which heavily impacted on the design of EJB-based systems. This thesis illuminates the changes since EJB specification version 2.0 comes and provides the best practices referring to entity beans and session beans analyzing their conceptual models in detail. Persistence layer and Web layer are the most important layers while building infrastructure of Web application. This thesis discusses the design and implementation of frameworks used in these layers in detail. And also discusses concerns of MVCF frameworks.Due to the weakness of entity bean model, it is undesirable to use entity bean as a data access solution for persistence layer. This thesis use data access object design pattern to obtain an abstraction separating business layer from persistent layer and use DTO design pattern to implement a JDBC-based framework.In this thesis, discusses the design for Comprehensive educational administration management information system, As the digitized campus system construction important constituent, enhances the teaching management the mass sum benefit key- educational administration management system computer, the network, also is realizes the school management modernization and the information important content. The system is design on MVCF framework, and fully used J2EE essential technical - EJB and DTO., After uses these technologies, this system has the multilayered overhead construction (the Web level, service level and data level) the coupling degree is low, is strong may the elasticity and is strong may the extended merit. At the same time, this system after the simple disposition, then may transplant to other systems in (for example Unix, Windows), but also has the platform irrelevant merit. Because this system has conforms to the party school educational administration special service overhead construction characteristic, depends upon may the extension and platform irrelevant may guarantee this set of system conveniently the party school displays the value in brothers, in the overall enhances the entire party school system special educational administration service the efficiency and the level.In this item, personally takes the item main participation, participates the item overall plan discussion, works the flow existence question in view of the old system and the at present, submits the demand analysis; The participation curriculum manages the subsystem the design and the development; The participation item later period technical maintenance work, and proposes work and so on improvement plan to the system deficiency.
