PREFACE

The rapid development of IT has strongly and greatly affected all aspects of socio- economic life Today, IT has become one of the most important drivers of development With the ability to digitize all kinds of information (numeric, graph, text, image, voice, sound.), the computer becomes a unified and versatile information processing means, performing many functions different capabilities on all forms of information in all fields: research, management, business The applications of Information Technology in the field of management are extremely important applications It not only frees up effort for managers but also brings accuracy and agility in management As a student of the Faculty of Information Technology, I am very happy when I have developed an application project of Student System Management Student information will be managed and sorted by name, date of birth, depending on the manager's choice In addition, the function of searching students by name, class and key will help administrators easily get the necessary information Score management function will allow administrators to enter grades for students and also provide tools that allow them to correct and update grades for students when needed Reward/Disciplinary Administration, allowing administrators to decide whether to reward or discipline a student attending the school Student statistics, allowing administrators to get information about students in the most intuitive and complete way Search student information, allowing management to get information about students quickly

Stemming from the above benefits with the permission and enthusiastic help of Mr Nguyen Minh Tuan, I would like to choose the topic "Student system management"

With this topic, I want to apply the knowledge I have learned in school along with the study of programming languages and environments to build an effective management system

Due to limited time and inexperience in research and practice, the report has many shortcomings I look forward to receiving suggestions from teachers to improve the topic Sincerely thank!

1 QUESTION

The University of Economics and Finance uses a professional training software to manage students and their learning process Build a program to simulate simple functions of the school's professional training program with the following requirements:

O The program has a login function

O_ Users are divided into two categories: trainers and trainers

O When logging in to the faculty user, if the login is successful, the score management function will appear, allowing to enter grades, edit scores, delete scores, update scores for existing students in the school and can find students by student code

O When logging in to the training staff user, the student management function will appear, including the functions, add a new student, delete a student and update

O_ Every time the lecturer updates the student's score, the program will recalculate the average score of each student, and display a list of the 3 students with the highest total score of each subject

2 DESIGN THE THEME

O_ Loading interface: is the page where when the user opens the software, a waiting page will be displayed, after loading to 100%, he will proceed to open the login form,

in order to create a more civilized and humane software

Figure 2 Login interface

O Login interface: is the security layer of the software to prevent unauthorized users from accessing and destroying data, if the login fails, an error will be reported until you enter the correct information and log in successfully will be redirected to the student management page (for training staff) and student score management (for

O Forgot password interface: when the user forgets the password of the account, requires entering the correct email before clicking submit, the software will automatically randomize the 6-digit password and send it to you by email

3 US ORGANIZATION REQUIREMENTS

O_In the organizational structure of the application, there is the use of interfaces, models, tools, and packages to facilitate the implementation of program settings in the most reasonable way and easy to correct if there are small errors

O Such organization helps us to solve problems quickly and optimize the time to create this application

4, FUNCTIONAL PROCESSING REQUIREMENTS

O Each time the Login button is clicked, the program must check whether the login information is correct, if it is correct, the message is successful, if it is incorrect, the login message is incorrect

O Instructors can only enter grades and cannot add new students Every time the lecturer updates the student's score, the program will recalculate the average score of each student, and display a list of the 3 students with the highest overall score

O Training staff can only add new students, cannot enter grades

5 ADVANCED FUNCTIONS

O Manage Student Points: lecturers (trainers) can add, delete, save, update scores for students and when clicking on a row on the table, the student's detailed data will be displayed on the tables respective components
