The development of online teaching platforms is an important means of reforming and innovating modern teaching methods. This paper focuses on the context of higher education marketing majors and investigates the design of a comprehensive teaching platform based on Web technology. By conducting research and analyzing the teaching requirements of the marketing major, using a B/S architecture, and employing mature technologies such as Spring Boot, MySQL, and Vue, the platform was developed through stages such as system design, database modeling, and functional implementation. It includes features such as video courses, teacher-student interaction, and assignment management. The platform supports the sharing of teaching resources, the networked teaching process, and the digitization of teaching evaluation information. Trial results indicate that this platform can meet the personalized and collaborative teaching needs of marketing majors and has achieved good teaching outcomes. This research provides a reference for the development of online teaching platforms for other majors and proposes prospects for further optimizing the platform, offering both theoretical and practical value.
