银行管理系统

一、　　客户

对于客户我们应该知道他的姓名、地址、联系电话、证件类型、证件号码等。

二、　　账户

对于一个客户，他在一个银行可以开通多个账号。所以对于一个账号，我们需要知道它的账户种类、账户号、开通此账户的客户信息，登录密码等。

三、　　存取款功能

对于客户存款，需要记录他的存款时间，存入的账户号，完成此次存款的员工编

号。对于客户取款，我们要知道他在用哪个取款，同时应该验证身份信息（卡号，密码）要知道该卡上的存款额，及此次的取款额。根据卡上的金额与所取金额的差值决定是否属于透支类型。若属于透支类型，需要知道客户以前的透支记录，即哪张卡上（卡型）什么时间（上一次透支日期）透支多少（金额）。若可以透支需根据客户的信誉度和经济能力确定用户的最大可透支额，用户根据其信息来透支所需金额。

四、　　转账

需要知道转账的卡型，卡号，密码（验证身份）。需要判断对方的账户。如果转账金额大于该卡现有金额则转账失败。

五、　　网络银行口令卡

网络银行有一张配套的口令卡，横排数字指示，竖排英文字母指示，组合成一个矩阵，每个矩阵填入一个三位数，如A8在登录时填入A8中的数字即可验证登陆。
