ssm三省学堂—学习辅助系统和论文答辩PPT
摘要
三省学堂-学习辅助系统是学校是学习辅助管理必不可少的一个部分。在学校学习辅助管理的整个过程中，学习辅助系统担负着最重要的角色。为满足如今日益复杂的管理需求，各类学习辅助管理程序也在不断改进。本课题所设计的三省学堂-学习辅助系统，使用java技术进行开发，它的优点代码不能从浏览器查看，保密性非常好，比其他的系统更具安全性。java还容易修改和调试，毕竟学校是在不断发展过程中，难免有更多需求，这点很重要。而且，本系统对学习辅助的管理，是为了满足学校更深层次的需求。除了上述优势外，本系统还具有查询迅速，搜索资料方便，可靠性强等特点。

Three provinces school - learning aid system is an essential part of school learning aid management. In the whole process of school learning aid management, learning aid system plays the most important role. To meet today's increasingly complex management needs, all kinds of learning assistance management programs are constantly improved. This topic designed by the three provinces of the school - learning assistance system, using Java technology for development, its advantages of the code can not be viewed from the browser, confidentiality is very good, more security than other systems. Java is also easy to modify and debug, which is important as schools continue to grow and need more. Moreover, the system of learning assistance management, is to meet the deeper needs of the school. In addition to the advantages mentioned above, the system also has the characteristics of quick inquiry, convenient data search and strong reliability.
