2、數(shù)量，系統(tǒng)自動(dòng)計(jì)算金額，輸入完畢后顯示應(yīng)付款，當(dāng)輸入實(shí)收額后，計(jì)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(dòng)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(jìn)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(gè)人登錄，消費(fèi)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(gè)人入庫信息修改更新4、計(jì)算功能基本計(jì)算功能，銷售額處理5、查詢功能資料庫信息查詢7、數(shù)據(jù)顯示功能保障客戶知情權(quán)，對(duì)系統(tǒng)
