1.基本功能演示?

1.1軟件登陸界面?

為實現多賬戶的登陸方式，故采用了標簽頁組合的方式，每個分頁面指向一個登錄窗口。?

1.2學生界面?

學生界面所需要的功能為課程分數查詢，功能較為簡單，采用了下拉框+編輯框+按鈕的方式實現，需要的特殊功能為學分預警。當科目分數小于60時，彈出彈框，并提示，當前科目分數小于60，要加油啦。?

1.3教師界面?

教師界面相對于學生界面略顯復雜，采用了列表+下拉框+編輯框的方式，首先通過下拉框的方式選擇姓名，隨之與其對應的其他幾項也會出現，可以根據科目下拉框選擇需要修改的科目，寫好后點擊修改?

1.4教務界面?

教務界面相較于教師界面包含了成績修改的功能，同時增加了對學生的增加?
