但是，目前许多银行在具体的一些业务流程处理过程中仍然使用手工操作的方式来实施，不仅费时、费力，效率低下，而且无法达到理想的效果。

本文针对上述问题，采用软件工程的开发原理，依据软件流程过程规范，按照需求分析、概要设计、详细设计、程序编码、测试、软件应用、软件维护等过程开发了一个银行ATM机管理系统系统。

1.1. 硬件环境⏹CPU : 1G以上⏹内存：512M以上1.2. 软件开发环境⏹操作系统：Window2003/XP⏹数据库连接驱动：Java project 集成开发环境⏹软件开发平台：Eclipse2.功能定义2.1. 储户模块⏹存款功能⏹取款功能⏹转账功能⏹查询余额功能2.2. 管理模块⏹存款管理⏹销户管理⏹报表管理3.数据之间的联系⏹一个客户可以有多个卡号。

而一个卡号只能被一个客户拥有⏹一个卡号可以有多条交易记录，而一条交易记录只能属于某个卡号4.系统用例图客户模块管理模块5.数据字典5.1银行卡数据项5.1.1.数据项：ID含义说明：唯一标识别名：无类型：长整型长度：描述：必填，主键5.1.2.数据项：卡号含义说明：银行卡的卡号别名：无类型：字符型长度：20描述：必填，唯一健，银行的卡号规则和电话号码一样，一般前8位代表特殊含义，如某总行某支行等。

假定该行要求其营业厅的卡号格式为：1010 3576 xxxx xxx开始,每4位号码后有空格5.1.3.数据项：密码含义说明：卡号的登录密码别名：无类型：字符型长度：6描述：必填，6位数字，开户时默认为6个“8”5.1.4.数据项：货币类型含义说明：该银行卡的使用的货币类型别名：无类型：字符型长度：20描述：必填，默认为RMB5.1.5数据项：余额含义说明：银行卡的余额别名：无类型：double长度：描述：默认值为06.项目任务书6.1 设计的目的和要求6.1.1 设计目的加深学生对面向对象概念以及JAVA面向对象程序设计思想的理解和掌握；使学生熟悉开发一个项目的基本过程，培养学生分析问题和解决问题的能力，增强学生的动手能力。

为后续学习和应用打下一定的基础。

6.1.2设计要求四个人一组协作完成，组长分工，并负责组内程序联试、文档质量检查及与教师联系。

每个学生必须独立完成你分工的课程设计部分。

所完成的项目软件需经指导教师检查认可。

6.2设计内容6.2.1.功能需求①用户登陆：检查用户使用的合法性。

②客户存款：客户按照自己的需求存入自己想存的钱③客户取款：可按100，200，500，1000元面额取款，并记录取款信息。

出款以数字显示。

④客户转账：客户不用等待人工转账，直接在ATM上很方便得进行转账。

⑤查询交易记录：如果客户对所取的钱有什么疑问的话可以查询交易记录。

⑥查询余额：客户可很方便的查询自己的余额，以至于取钱不用超支。

⑦退出；当客户把一切都做好后就可以退卡。

6.2.2.信息需求①客户存折信息表客户帐号客户姓名客户密码客户存款日期客户存款额（元）②客户取款信息表客户帐号取款日期时间取款金额7.项目开发计划7.1 编写的目的我们的开发目的是在于了解ATM柜员机开发项目的流程，把在开发过程中对各项工作的人员、分工、系统资源条件等问题的安排用文档形式记载下来，以便根据本计划开展和检查本项目工作，保证项目开发成功。

管理员进入管理员系统，可以查看和修改用户的信息，管理员系统是基于网络环境，卡号应从服务器的数据库随机抽取生成的。

另外，管理员系统还应该对用户实现开户、销户、查询、修改等功能。

9.项目设计说明书9.1 编写目的此软件是为方便广大存取用户，解决存取受时间限制的弊端，它具有取款，转帐，查询余额，修改密码的功能。

用户操作完可取卡退出。

9.2 系统总体结构设计10.详细设计首先建立一个名为“ATM柜员机.jpx”的工程文件，然后在工程文件中建立一个名为“ATM.java”的应用程序，然后开始一下设计。
