Design And Implementation System Of Online Examination

This system is designed based on JSP online examination system. Systemprovides three user, administrator, teachers and students respectively. Students canchoose to log in the online examination module. When take a subject test, thesystem will randomly selected from the subject question bank papers for students toanswer questions. After students complete answers and submit papers, onlineexamination system will automatically according to the answers of studentsevaluation objective topic section, and in accordance with each type of questionscore, give the examinee scores. Subjective topic section will have a group ofteachers artificial modification, when teachers refer to the test paper, the system willremind teachers grade subjective item parts. Batch volume teacher corrects logged into view corresponding subjects examinee examination paper, and after you submitscores, the system will be done according to this subject scores distributionautomatic information statistics, including the scale of the number and pass rate,bringing teachers understand the examination condition, better analysis of students’learning situation. Students can log in again at this time for middle schoolmanagement module to view your test scores, and can view the own paper as well asthe correct answer to each question, convenient students self‐improvement topromote learning. And super administrator can log in to manage the whole system,including all the users of the system information maintenance, the test setup, as wellas to the test question setting and so on various subjects.This system based on the principle of convenient and easy to use, USES B/Sdevelopment model, is a complete system running on the browser. According to thestructure and the artist, mainly used in HTML, javascript, CSS cascading style, etc.And the background systems used in the JSP/servlet. System mainly on the MyEclipsedevelopment completed, build a SQL Server2005as the database developmentenvironment, the Apache TomCat7x as the web Server.This paper adopts the model of software engineering, structural clarity. First this paper introduces the background of this system design, design the basic functionof, and the profound significance of the design. Then detailed elaborated the systemdesign and implementation process, from initial needs analysis, to the overall designof the whole system, and refinement to the database and the detailed design of eachfunction module. Then this paper made a detailed introduction to the systemimplementation, and system operation screenshots. This paper introduces thesystem finally complete the process of performance testing and analysis of theresults.
