原创
通过JSP+JDBC制作一个简单的操作数据库中表信息的系统。
总体界面如下，一共有5个功能块。
功能一：列出全部学生
功能二：按条件查询学生
功能三：新添加学生
功能四：按条件删除学生
功能五：按条件修改学生
JSP页面介绍(连接的数据名称为DB OF CWM，操作的表为Student)：
综合数据库系统总页面.jsp —— 设计总体页面的框架

综合数据库页面_up.jsp —— 设计总体页面的上方（即图中的学生数据库管理系统）

综合数据库页面_down_left.jsp —— 设计总体页面的下方的左边（即显示五个超链接的功能块）

综合数据库_down_left_列出全部学生.jsp —— （连接数据库显示表Student的所有学生信息，数据库连接密码自己修改）
