摘 要
使用旧方法对课程辅导信息进行系统化管理已经不再让人们信赖了,把现在
的网络信息技术运用在课程辅导信息的管理上面可以解决许多信息管理上面的
难题,比如处理数据时间很长,数据存在错误不能及时纠正等问题。
这次开发的课程辅导网站有学生,教师,管理员。
管理员功能有教师信息管理,学生信息管理,教学资源管理,推荐课程管理,
公告信息管理。
教师功能有教学资源管理,推荐课程管理,公告信息管理。
学生功能有查看和收藏教学资源信息,查看和收藏推荐课程信息。
经过前面自己查阅的网络知识,加上自己在学校课堂上学习的知识,决定开
发系统选择 B/S 模式这种高效率的模式完成系统功能开发。这种模式让操作员基
于浏览器的方式进行网站访问,采用的主流的 Java 语言这种面向对象的语言进
行课程辅导网站程序的开发,在数据库的选择上面,选择功能强大的 MySQL 数
据库进行数据的存放操作。
课程辅导网站被人们投放于现在的生活中进行使用,该款管理类软件就可以
让管理人员处理信息的时间介于十几秒之间。在这十几秒内就能完成信息的编辑
等操作。有了这样的管理软件,课程辅导信息的管理就离无纸化办公的目标更贴
近了。

Abstract
The use of the old method to systematically manage the course guidance
information is no longer trusted by people. Applying the current network information
technology to the management of course guidance information can solve many
problems in information management, such as processing data for a long time. There
are problems such as errors that cannot be corrected in time.
The course guidance website developed this time has students, teachers, and
administrators.
The administrator functions include teacher information management, student
information management, teaching resource management, recommended course
management, and announcement information management.
Teacher functions include teaching resource management, recommended course
management, and announcement information management.
The student function includes viewing and bookmarking teaching resource
information, viewing and bookmarking recommended course information.
After the network knowledge I checked before, plus the knowledge I learned in
the school classroom, I decided to choose the B/S mode as a high-efficiency mode for
the development system to complete the system function development. This mode
allows the operator to access the website based on the browser. The mainstream Java
language, an object-oriented language, is used for the development of the course
guidance website program. In the selection of the database, the powerful MySQL
database is selected for data analysis. Storage operation.
The course guidance website is used by people in their current lives. This
management software allows managers to process information within a dozen seconds.
Information editing and other operations can be completed within these ten seconds.
With such management software, the management of course guidance information is
closer to the goal of paperless office.
