Panzhihua Iron And Staff Training Online Examination System And To Achieve

PanGang is a large-scale state-owned iron and steel enterprise, there are 100895 registered employees in it now. Workers trainings of PanGang are rich in content and varied in forms, the human and material consumptionof it are significant. So, the development of a computer network online examination system has great practical value and necessity.Along with the development of the computer network technology and the database technology, the online examination system is used widely because of its high efficiency and convenience. Compared with traditional methods of examination, the network online examination system save or optimize a lot of test steps rationally, save the test fee ,thus it enhances the efficiency of the examination greatly. So, it is of great significance to study how to use computer networks technology to build an efficient online examination system.The PanGang Workers Training Network Online Examination System is based on the B / S mode.It is developed by using the JSP programming language, it used the Servlet / Jsp of the J2EE system(jdk1.6.0), used Tomcat5.5 as Web Servers, used SQL server2000 database as DBMS development tool,and used Power Designer as data modeling tool.The PanGang Workers Training Network Online Examination System is divided into three subsystems: the Online Examination Subsystem, the Teacher Management Subsystem and the System Management Subsystem.It can realize important functions such as test paper Automaticaly generating, Test Item Bank updating, Examination papers Random access, users information Maintenance and Management, Examination paper information Maintenance and Management, score information Maintenance and Management,and Data backup and recovery. Because it uses the connection pools to connect to the database, the system can implement a certain number of candidates to online exam at the same time. The system has the friendly interface, simple to use, easy to update information, query robust, extensibility of the system is strong. The thesis expounds the system design process from the development background, systems analysis, system design, coding and testing, evaluation and maintenance, the difficulties and the solutions, and so on. Among them,it introduces the implement key points of each module from three areas such as the design analysis, Design interface diagram and Design features detailly.
