15、更，以便学生能正常上课，还有对学生信息的安全性及完整性，安全性的要求要鉴别老师及学生信息的信息是否准确，如果是正确信息要对老师及学生的信息进行保护。而完整性就是确定安全性的同时不容许信息缺漏，使各种信息必要时联系起来，相同信息的重复。第二部分、设计实训的题目功能(1) 程序界面及代码：（2）学生成绩管理系统部分代码如下： namespace 学生成绩管理系统 partial class Frmmain / / Required designer variable. / private System.ComponentModel.IContainer components = null; / /
