Due to the above requirements, using related technologies, the user interface is unified as a browser, the front-end interface operation is developed using JSP technology, and the back-end database uses Microsoft SQL Server 2000 as the database server, as well as other technologies such as tomcat. Designed and developed an online audio-visual management system. Analyze online shopping, divide functional modules, analyze the database model, and design the database structure and application program from this. The online audio-visual management system designed in this article meets the five needs of online purchase, product information introduction, publication of product information reviews, background information management, and order processing. It is used for users to inquire and purchase video discs online, providing users with a convenient, fast and economical online shopping environment.
