1、需求分析： 在对软件工程相关知识学习之后，我们对设计软件有了基本的认识和一些应用技能。在数据库的课程设计中，我们计划做一个小型的银行储蓄管理系统，包括了基本的存取转，和管理员对日常工作的管理功能。功能设计： (1).客户：包括存款，取款，转账，查询余额，查看流水，密码修改功能 (2).管理员：新增用户，删除用户，查看用户，员工绩效，VIP用户判别，储备金预警分析。3.功能流程图：详细设计：1.E-R图模型2.根据E-R图设计关系表 (1).银行信息表（bank）字段名字段类型及长度允许空主键 说明Bid nchar(9) no PK银行号Bname nchar(20) no银行名Bmoney

2、numeric(20,3) no银行余额 （2）.客户信息表（custom）字段名字段类型及长度允许空主键 说明Cid nchar(9) no PK 客户IDCname nchar(10) no 客户姓名Cpass nchar(10) no 密码Ctime nchar(20) no 注册时间Bid nchar(9) no 所在银行行号 外码（Bank（Bid）Crmoney numeric(10,3) no 账户余额Cphone nchar(11) no 客户电话 (3).员工（管理员）表（staff）字段名字段类型及长度允许空主键 说明Sid nchar(9) no PK 员工IDSname

3、 nchar(10) no 员工姓名Spass nchar(10) no 登陆密码SItime nchar(20) no 入行时间Sphone nchar(11) no 联系电话 (4).流水信息表字段名字段类型及长度允许空主键 说明Oid nchar(9) no PK 流水号Cid nchar(9) no 客户ID 外码（Custom（Cid）Bid nchar(9) no 银行ID 外码（Bank（Bid）Sid nchar(9) no 员工ID 外码（Staff（Sid）Otype smallint no 操作类型Otime nchar(20) no 操作时间Omoney numeric
