数据库设计以及源代码系统建设详细设计1.数据库设计管理员用户表信息：字段名称类型大小字段描述管理员ID 自动编号长整型管理员身份识别管理员名称文本50 管理员登陆名称密码文本50 管理员登陆的密码身份文本50 有别于学生登陆界面学生用户表：字段名称类型大小字段描述学生ID 自动编号长整型学生学号学生名称文本50 学生名称密码文本50 学生登陆的密码身份文本50 有别于管理员登陆界面学生信息表：字段名称类型大小字段描述学生ID 自动编号长整型学生学号学生名称文本50 学生名称电子邮文本50 学生的电子邮箱箱备注/ / 学生的其他信息性别文本50 性别入学时文本50 学生入学的时间间班级文本50 所在班级专业文本50 所学专业2 系统程序文件设计与编写与数据库连接的代码：<% db="message.mdb"set
