[教育]銀行atm數(shù)據(jù)庫設(shè)計

1、ATM取款機系統(tǒng)數(shù)據(jù)庫設(shè)計,問題描述,某銀行擬開發(fā)一套ATM取款機系統(tǒng)，實現(xiàn)如下功能：1、開戶（到銀行填寫開戶申請單，卡號自動生成）2、取錢3、存錢4、查詢余額5、轉(zhuǎn)賬（如使用一卡通代繳手機話費、個人股票交易等）現(xiàn)要求對“ATM柜員機系統(tǒng)”進行數(shù)據(jù)庫的設(shè)計并實現(xiàn)，數(shù)據(jù)庫保存在D:\bank目錄下，文件增長率為15% 。,問題分析-1,,用戶信息表：userInfo ：,問題分析-2,銀行卡信息表：cardInfo,問題分析-
