Chapter 3 Requirement Analysis
3.1 Overall System Requirement Analysis
This system is aimed at teaching staff and fresh students , divided into teachers, teaching secretaries and students, students and teachers perform business in the foreground, and teaching secretaries deploy business in the background. Students can log in, select topics, check personal information, submit documents and evaluate, etc. Teachers can perform operations such as setting questions and uploading documents, and teaching secretaries can manage and deploy relevant data information.
3.2 System detailed requirement analysis
Main functions of students:
(1) Log in: log in according to user name and password.
(2) Topic selection: View all topics and select graduation design topics.
(3) Topic opening: Download the topic-related document template and upload the topic opening report.
(4) Upload the interim report: upload the relevant documents of the interim report.
(5) Defense: defense application, upload relevant documents.
(6) Feedback: Evaluation of the instructor.
Main functions of teachers:
(1) Topic management: add, delete, check and modify topics.
(2) Topic status management: Modify the topic confirmation status.
(3) Interim report management: download relevant documents of interim report
(4) Defense: upload relevant documents and record the defense process.
(5) Achievement management: Grading the graduates and calculating the total score of the defense.
(6) Feedback: evaluate the graduates.
The main functions of the teaching secretary:
(1) Log in: log in according to the user name and password.
(2) Management of user information, user rights, questions, and question status.
