On-line examination system base on JAVA

Student : CHAO SUN supervisor: WEI MING XIAO 【ABSTRACT】On-line examination system the aim is carry out examination of have no the paper turn a management, can carry on through Internet net or bureau area net to some examinations of categories, convenient school square test the management of duty, also convenient the examinee is particularly suitable for examinee to distribute widely and not easily concentrated of long range education.I mainly develop the system-JAVAEE of the backstage management's on-line examination management sub- system of system and it includes to try the management, on-line creation of a management, examinee to try book, control the constitution that the student examine and try an examination and approval etc. function.This thesis mainly introduced to manage the analysis, design of the sub- system and all processes of the development to JAVAEE's on-line examination.Make use of ER diagram, procedure flow chart etc. to on-line manage the design process of sub- system to carry on expatiation.The full text is totally divided into the design, key technique of the analysis, system of the development project, need to solve, conclusion five part.Develop the main introduction in the project develops on-line examination system purpose, development project of choice and development frame of the assurance of technique;The need analysis introduced the total need of the on-line examination system and the function request of each mold of system piece;The system design introduced the design, system mold of the instruction thought, database of system design the design of the piece;The key technique introduced at concrete carry out need some techniques for solve, such as development frame of integration technique, development frame with The database link and the backup and revivification of data. Keyword: Servlet ,JSP, JAVA,MySql, Model of B/ S
