Assignments And Examination System Based On J2ee Platform Design

This thesis discusses a J2EE solution from analysis,design to implementation the R&D practice of Test and Homework System(THS),one of the research issues of China's National Tenth Five-Year Key Science and Technology Project,E-education Key Technology and Demonstration Project.To obtain an extendable and transplantable system,and integrate subsystems together for convenience,it is decided to construct the project on the J2EE platform.The thesis brings forward the solution by five parts.At first,it points out the skills such us Java,J2EE,EJB,JSP and design module of THS.Secondly,it discuss THS analysis and design,indicate the requirements analysis,architecture design,function design and data-base design.In this part,the thesis illustrates the utility of the use case during requirements analysis and emphasizes the important role of architecture design during the software process after present the concept of architecture,and discusses the architecture process and key point in detail during the process of THS architecture design,so as data-base design.In the third part,the thesis presents the object-oriented design process of some functionnal parts.The R&D practice of THS fully proves that the J2EE solution discussed in this thesis is very effective,and also,it can provide directive function to other J2EE system development and be used for reference.
