看下吧,有什么不足的請指出來
工資管理系統(tǒng)主要功能和特點：
1 操作簡單方便
采用國際流行的下拉菜單，全WINDOWS操作形式，界面新穎，全面支持鼠標操作，功能齊全。
2 任意設定工資項目
系統(tǒng)除姓名、人員編號、部門編號、部門名稱、應發(fā)工資、實發(fā)工資、納稅等內(nèi)定項目不能刪除(長度可以改變)外，其它項目(如各種補貼及各種扣款)均可由用戶自行定義(包括增加、刪除、修改長度及小數(shù)位等)，工資項目總數(shù)可多達255項。當修改或刪除工資項目時，自動檢查工資計算中與該項目有關的計算公式，并作相應處理。
3 任意定義工資計算公式
用戶可將某些工資項目(如加班費、應發(fā)工資、納稅等)定義為計算項目，然后定義其計算公式及使用條件，可滿足各種復雜的計算。
如: 項目 公式 條件
每日工資 基本工資/26
月加班費 加班天數(shù)*每日工資 類別=
對數(shù)據(jù)庫進行增刪改查？
以下是 sql server 2013+java.實現(xiàn)的是對MSC對象的增刪改查.
需要下載連接驅(qū)動程序：com.microsoft.sqlserver.jdbc.SQLServerDriver
網(wǎng)上搜一下就行
