Design And Implement Of A Web-based System For Achievement Management Of Students

Management of students'scores is an important integral part of daily routine in schools. The gradual expansion of recruitment in colleges and universities and the innovation of recognition system have resulted in constant increase of the number of students in colleges and universities; however, the number of student management personnel decreases relatively and the traditional management methods are basically not suitable to the requirements of the new situation. Nowadays when the computer technology is developing rapidly, therefore, it is feasible and essential to apply database technology in student information management. Network management of student information in colleges and universities can both improve the working efficiency and increase the working level.The integral development process of students'score management system is highlighted herein. The system development environment and tools are introduced. The design philosophy and design process are fully described. The idea of database establishment and the interrelation between data sheets, etc are detailed. The realization process and detailed design process of system functions are analyzed in detail. In plotting the simple system function module diagram, efforts are made to clearly indicate the design philosophy and the planning and specific realization of the complete program design.As required, for the project of students'score management system, modularization design philosophy is introduced in order to decompose the complicated problem into several minor problems to be easily solved. Thus, the former problem becomes easy to solve. Modularization design divides large-scale software into small interrelated modules with relatively independent functions based on certain principles. Each of the modules will fulfill a specific subfunction. These modules are integrated into a whole to fulfill a designated function to meet the requirement of the problem. The software structure is well defined and can be tested and debugged readily so that the reliability and modifiability of the software are improved, which facilitates organizational management for software development. To be specific, software Macromedia Dreamweaver MX by Macromedia Company with JSP development technology, friendly interface and powerful function is used for this system. The server side script is compiled with JAVA script, so is the client side script. SQL Server 2000 database is used. TOMCAT 5.0 is used on server.By application of this system, students are able to inquire about the information of scores they obtained for their own courses at the term end, incl. the serial number of courses selected, the name of courses and the scores. After logging in with the initial cipher, the student may modify his/her own cipher. Teacher can type in students'score information, modify the login cipher and delete, add and modify student information. In addition, teacher information can be established and managed, incl. name, gender, major and professional tile of teachers and remark, etc. The system administrator can add, delete and modify course information, class and student information and teacher information and manage students'scores, etc. The teaching management personnel can manage student, teacher and course information, etc.In this system, the client side layer is separated from the database layer so that it is impossible on the client side to contact the intrinsic database or carry out any illegal modification or damage. Thus the database is protected effectively, safely. The functions are complete and the user can use it conveniently, simply. Complete security is set. All this has greatly mitigated the work load of operators and users and improved the working efficiency of students'score management and the informatization level of schools.
