2、及密碼，驗證后方可 使用系統(tǒng)。2. 收銀操作：收銀員逐條輸入商品編號及數(shù)量，系統(tǒng)自動計算金額，輸入完畢 后顯示應(yīng)付款，當(dāng)輸入實收額后，計算出找贖值。3. 交易完成后按一定格式顯示回單（格式參照一般超市中的打印小票） 。4. 保存所顯示的回單。5. 自動按銷售情況更新商品信息文件中的數(shù)據(jù)。6. 查詢收銀員銷售信息。7. 瀏覽庫存商品信息。1.2 系統(tǒng)功能需求分析本系統(tǒng)應(yīng)具有以下功能：1、文件操作功能進行商品信息管理，以文本的形式保存商品最新信息2、數(shù)據(jù)輸入功能 個人登錄，消費商品基本資料的輸入，銷售信息輸入等3、數(shù)據(jù)添加、修改、刪除功能 商品數(shù)據(jù)更新，個人入庫信息修改更新4、計算功能基本計算功能
