Summary

The coverage of the Internet and the popularization of computers and mobile phones have raised people's communication to the level of network information. It was in this environment that the forum system was born, and it is deeply loved by users.

The student forum system of this college uses Java technology, MYSQL database stores data, and is developed based on the SSM+Vue framework. During the entire development process of the website, we first conducted a demand analysis on the system and designed the main functional modules of the system. Secondly, we carried out overall planning and detailed design of the website. Finally, we conducted system testing on the college student forum system, including test definition and testing. Methods, test plans, etc., and the test results were analyzed and summarized, and then the system's shortcomings and areas for improvement were obtained, which facilitated future system maintenance and expansion.

This system has reasonable layout, harmonious color matching, clear frame structure design, simple operation, clear interface, convenient management, complete functions, etc., and has high use value.

Abstract

The coverage of the Internet and the popularization of computer phones have made people's communication rise to the level of network informationization. The forum system was born under such an environment, and it is deeply loved by users.

The student forum system of this college applies Java technology, MYSQL database stores data, and is developed based on the SSM+Vue framework. In the entire development process of the website, firstly, the system needs analysis, and the main functional modules of the system are designed. Secondly, the overall planning and detailed design of the website are carried out. Finally, a system test is carried out on the college student forum system, including test definitions and tests. Methods, test schemes, etc., and the test results are analyzed and summarized, and then the deficiencies of the system and the areas that need improvement are drawn, which provides convenience for future system maintenance and expansion.

The system has the advantages of reasonable layout, harmonious color matching, clear frame structure design, simple operation, clear interface, convenient management, and complete functions, and has high use value.
