Weekly -- sequence diagram of the Course Management System for the design of the network teaching resource platform

 

From the initial selection of Practical Training Questions to contact the teacher to understand the needs of the questions, and then our team analyzed the functions that this project should have, and finally the division of work to everyone. So far, I have learned a lot in this process for three weeks, and I have only been able to practice it, you will be able to learn the mysteries of the solution.

Recently, many documents have been written. Whether it is mobile game development documents or demand analysis reports on practical training questions, this not only gives me a deeper understanding of the project, at the same time, the use of wordsoftware has been further improved. Today, I heard from my teacher what parts of the document need to be modified: I suddenly realized that these documents were so demanding! In the future, you should urge yourself to take this document more carefully.

In the design and implementation of the network teaching resource platform, I am responsible for the curriculum management system. The main functions of this project are as follows:

◆ The Administrator manages the course information, including deleting the course;

◆ The Administrator manages user information, including adding, deleting, modifying, and querying users;

◆ Instructors manage course information, including adding, deleting, modifying, and querying courses;

◆ Students can view the course information.

 

 

The sequence diagram of the Course management system is as follows:

1) add and delete courses and user sequence diagrams as administrators

Through interaction with the Management window, the system administrator can add or delete courses, update courses, and add or delete users. The specific operations are completed by the interaction between the management window and the database, the results after the Administrator operation are displayed on the page.

2) The user queries the course sequence diagram

To log on to the system, you must first interact with the logon window and enter the user name and password. The login window is responsible for interacting with the server. The user name and password entered by the user are sent to the server, and the server interacts with the database to verify the validity of the user name and password. If the verification is successful, a success is returned, if verification fails, an error is returned. The server displays the information to the user in the logon window.

3) add or delete a course sequence diagram as a instructor

Through interaction with the Management window, instructors can add or delete courses and update courses. The specific operations are completed by the interaction between the management window and the database. The instructor operation results are displayed on the page.
