On Design And Implementation Of A Students' Information Management System Based On B/S Model

Student information management system is very important to the management of colleges and universities.Student information shows the characteristics of large amount of data,a wide range of personnel and frequent update and so on.These new features pose new challenges for effective,large-scale information management system.The naive manual management has been unable to meet the needs of large-scale effective management of information.This paper designs and implements a student information management system based on B/S mode.Through the separation of business logic and the technology of light client,the system can improve the efficiency of student information management and realize the systematic,scientific,standardized and automatic management of student information.Specifically,the main contents of this paper include the following aspects:Firstly,this thesis studies and designs the basic function of student information management system based on B/S mode.The system includes three main features:First,the system achieves a light client data access mode through the B/S design pattern,which reduces the difficulty of the client installation,but also improves the applicability of the system;Second,the system realizes the basic functions through friendly interface and user-friendly management system,not only improves user efficiency,but also enhances the user experience,such as the user can accurately locate the query information required through the query,and can update the information at any time;Third,the system controls the technical means to achieve the isolation between users through the authority management,which prevents the data tampering between users and also improves the user's privacy.Secondly,this thesis studies and designs the secure data transmission of the student information management system.The secure data transmission has always been an important aspect to be considered in system design.To this end,this paper studies and designs the secure data transmission through the data encoding,where the data is encoded before transmission and the data is decoded in the receiver.In this way,the state of the original data is changed by encoding,where some data could not decode to the original data even if part of the data is intercepted.Thus,the encoded data transmission achieves the secure data transmission.Finally,we study and design the reliable data storage for the student information management system.Reliable data storage has been the pursuing goal of the system.To this end,this paper studies and designs the student information management-system,which adopts the data encoding technique to ensure data reliability.Specifically,the data is encoded before putting into the data base,where the datareliability is ensured by the redundancies.After the completion of the coding,the data stored in the form of encoded in the database.The adoption of the encoding techniques ensures that the data could be recovered even part of the data gets lost,which ensures the data reliability.
