Development and Design of Online Examination System for Teaching Reform of Marketing Course Based on UML

In order to effectively cultivate the professional ability of marketing students through the online examination system, this paper designs and implements an online examination system to meet the daily teaching assessment of school. We analyze the function and performance requirements of the system, and use UML technology to model the system, and use JSP + JavaBean technology to realize the examination system based on distributed three-tier web application structure, according to the analysis of the whole business process of the examination,. Then, for the characteristics of the project, the system modules are divided and the key technologies of each function are described. Finally, using B/S architecture and Java language to complete the system programming, we make full use of COM+ components to optimize the performance of the system. The running test results show that the coupling degree between each module is reduced, which effectively solves the important problem of online examination management in curriculum reform.
