用java写银行ATM和分行和总行的系统

Question

1.有若干个工商ATM，每几个工商ATM连接一个工商支行服务器，所有的工商支行服务器连接工商总行服务器。
2.工商支行服务器存储在该支行开户的用户的账号和密码，工商总行服务器有此备份。
3.模拟用户在一台工商银行ATM上输入账号和密码，工商总行服务器验证账号和密码是否匹配。
若成功，ATM提供查询、存款、取款业务。
若失败，ATM提示用户重新输入密码。
4.若用户在ATM上存取款，则工商支行服务器上该用户的余额相应增减，工商总行服务器上该用户的余额也相应增减。
5.农行的情况同上，用户在工商ATM上输入农行账号和密码，工商银行总服务器向农行总服务器发出请求。
6.农行总服务器验证账号和密码是否匹配并返回信息。
若成功，在工商ATM提供查询、存款、取款业务。
若失败，工商ATM提示用户重新输入密码。
7.若用户在工商ATM上存取款，则农行总服务器上该用户的余额相应增减。
