随着信息化时代的到来，管理系统都趋向于智能化、系统化，平面设计课程在线学习平台系统也不例外，但目前国内的市场仍都使用人工管理，市场规模越来越大，同时信息量也越来越庞大，人工管理显然已无法应对时代的变化，而平面设计课程在线学习平台系统能很好地解决这一问题，轻松应对平面设计课程在线学习平时的工作，既能提高人力物力财力，又能加快工作的效率，取代人工管理是必然趋势。

本平面设计课程在线学习平台系统以ssm作为框架，b/s模式以及MySql作为后台运行的数据库，同时使用Tomcat用为系统的服务器。本系统主要包括以下功能模块：首页，个人中心，学生管理，教师管理，课程类型管理，课程学习管理，试题讲解管理，作业信息管理，作业提交管理，作业批改管理，在线测试管理，试题管理，我的收藏管理，在线讨论，系统管理，考试管理等模块，通过这些模块的实现能够基本满足日常平面设计课程在线学习管理的操作。

本文着重阐述了平面设计课程在线学习平台系统的分析、设计与实现，首先介绍开发系统和环境配置、数据库的设计，接着说明功能模块的详细实现，最后进行了总结。

Abstract

With the advent of the era of information technology, management systems tend to be intelligent, systematic, graphic design courses online learning platform system is no exception, but the current domestic market still use manual management, the size of the market is more and more big, at the same time, the amount of information is becoming more and more big, artificial management has clearly unable to cope with the changes of The Times, The graphic design course online learning platform system can well solve this problem, easy to cope with the usual work of graphic design course online learning, can not only improve human and material resources and financial resources, but also speed up the efficiency of work, replacing manual management is an inevitable trend.

The online learning platform system of the graphic design course takes SSM as the framework, B/S mode and MySql as the database running in the background, and Tomcat is used as the server of the system. The system mainly includes the following functional modules: Home page, personal center, student management, teacher management, course type management, course learning management, test explanation management, homework information management, homework submission management, homework correcting management, online test management, test management, my collection management, online discussion, system management, examination management and other modules, Through the realization of these modules can basically meet the daily graphic design course online learning management operation.

This paper focuses on the graphic design course online learning platform system analysis, design and implementation, first introduces the development system and environment configuration, database design, then explains the detailed implementation of functional modules, and finally summarized.

Key words: Graphic design course online learning platform system; ssm; MySql database; Tomcat;
