java项目ATM银行系统源代码

项目设计成绩评定表模拟ATM柜员机系统摘要本ATM系统的目的就是建立一个客户平台，用户使用此平台进行查询余额、存款、取款、转账、修改密码等业务办理。

相对于柜员操作一样的，不过ATM 系统有的功能有权限设置，一些功能只有银行柜员才能进行的业务办理。

ATM取款系统的针对的用户群是使用此软件系统的用户，用户做为系统的服务群体，可以使用数据库已有的账号与密码，登陆ATM系统。

当用户成功登陆后就可以根据用户的需求进行各项业务的办理，办理完所有的手续后，用户的输入的新资料以及办理的业务处理后的信息都会反馈到数据库并且都会存入到数据库中。

这样用户就完成了办理业务。

Relative to the same teller operations, but the ATM system, permissions settings, some functions, some functions be carried out only a bank teller, handling the business.ATM withdrawals of the user base for the system is to use this software system, users, as a system service groups, you can use an existing database account and password, log ATM system. When the user after a successful landing can be carried out according to the needs of users of the business of handling, handling all the formalities finished, the user's input of new data and the processing of business information will be processed back to the database and will be deposited into the database . So that the user completes the processing business.Key words: ATM Jcreator Java目录摘要 (2)ABSTRACT (3)1 系统分析 (6)1.1背景分析 (6)1.2系统功能 (6)1.3主要问题 (7)1.4开发工具与环境 (7)1.4.1开发工具 (7)1.4.2开发环境 (7)2 系统整体设计 (8)2.1设计思想 (8)2.1.1功能模块划分 (8)2.2数据库设计 (9)3 系统详细设计 (10)3.1系统总设计 (10)3.2 登陆界面设计 (11)3.3查询界面设计 (13)3.4存、取款界面设计 (15)3.5转账界面设计 (16)3.6修改密码界面设计 (17)参考文献 (19)心得体会 (20)附录1：答辩记录表 (21)附录2：系统程序代码 (21)1 系统分析1.1背景分析随着信息时代科技的飞速发展，使用ATM取款机、计算机等技术的发展，不仅提高了工作效率，而且大大的提高了其安全性。

本科毕业设计论文基于JAVA的银行账户管理系统的设计与实现摘要随着我国信息产业的迅速发展以及中国加入世界贸易组织，国内外银行之间的竞争也越来越激烈，如何发展业务以吸引更多顾客是各银行面对的当务之急。

于此同时，账户管理是银行业务流程过程中十分重要且必备的环节之一，并且现在银行的业务越来越多，吸引的客户也越来越多，银行账户的高效管理就越显重要。

银行账户管理系统是针对银行账户的日常管理而设计，操作方便而且界面简洁，使用Java作为编程语言，Eclipse作为开发工具，Mysql作为后台数据存储，采用软件工程的开发原理，按照需求分析、概要设计、详细设计、程序编码、软件测试等过程进行规范设计。

本银行账户管理系统具有良好的容错性，在出现误操作时能及时的给出相关错误提示，以便于用户及时地更正。

设计过程思路清晰，模块划分简洁，设计各阶段分工明确，极大的提高了本系统的实现。

How to develop business to attract more customers at the moment is the problem many banks confront. At the same time, account management is one of the important and necessary links in the process of bank business. Besides, the bank businesses nowadays are becoming larger and larger, and more and more customers are attracted, so efficient management of bank account seems extremely important.Bank account management system is designed for the daily administration of bank account. It is easy to operate and has a concise interface. It uses Java as a programming language, apply Eclipse as development tools, choose Mysql as the background data storage and adopt the software engineering evelopment principle. It is designed according to the requirement analysis, general design, detailed design, program code, software test and so on.This bank account management system is good at fault tolerance. When dealing with the wrong operation, it can point out the related errors in time , so that users can correct the errors timely. The thinking of the design process is clear , the module partition is concise and the division of each stage is explicit, which contribute a lot to the achivement of this system.Keywords: account management;software engineering; Java;Eclipse; business process目录第1章绪论 (1)1.1概述 (1)1.2可行性分析 (1)1.2.1技术可行性 (1)1.2.2经济可行性 (1)1.2.3管理可行性 (2)1.3设计意义 (2)1.4设计目标 (2)第2章开发工具及运行环境 (3)2.1开发工具 (3)2.1.1 Java语言特性 (3)2.1.2 Eclipse (3)2.1.3 Mysql与Navicat for Mysql (4)2.2运行环境 (4)第3章系统需求分析 (5)3.1功能模块分析 (5)3.1.1用户注册 (5)3.1.2用户登录 (5)3.1.3用户主菜单 (5)3.1.4存款功能 (6)3.1.5取款功能 (6)3.1.6转账功能 (6)3.1.7查询功能 (7)3.1.8修改密码 (7)3.1.9返回功能 (8)3.2业务流程分析 (8)3.3数据流程分析 (8)3.3.1系统关联图 (8)3.3.2顶层图 (9)3.3.3数据流图 (9)第4章数据库分析 (10)4.1数据库需求分析 (10)4.2数据库概念结构设计 (11)4.3数据库逻辑结构设计 (11)4.4数据库结构的实现 (12)第5章系统设计 (14)5.1用户实体 (14)5.2界面代码设计 (15)5.3数据库的连接 (17)5.4功能模块的实现 (18)第6章系统测试 (19)第7章总结与展望 (25)7.1总结 (25)7.2展望 (25)参考文献 (26)致谢 (27)附录 (28)第1章绪论1.1 概述进入21世纪之后，随着科技的飞速发展和社会进步，尤其是计算机在大范围的普及，人工智能化的计算机应用也逐步的由大规模科学计算的海量数据处理转向大规模的事务处理和对工作流的管理，这就产生了以计算机为核心，以数据库管理系统为开发环境的管理信息系统在大规模的事务处理和对工作流的管理等方面的应用，特别是在银行账户管理之中的应用日益受到人们的关注。

UML建模语言7种图(以银行ATM系统为例)分类：JAVA2010-04-21 20:40 2911人阅读评论(0) 收藏举报uml语言活动作业优化1 用例图：描述了系统提供的一个功能单元。

以一种可视化的方式理解系统的功能需求，"角色"与系统内用例之间的关系。

本例中，参与者"银行储户"和ATM机。

简化后的ATM机仅有取款、存款及其余功能。

其余功能不做详细说明。

2 类图：显示系统的静态结构。

逻辑类、实现类，实现类就是程序员处理的实体。

类在类图上使用包含三个部分的矩形来描述，如图2所示。

最上面的部分显示类的名称，中间部分包含类的属性，最下面的部分包含类的操作（或者说"方法"）。

本例中许多单个的帐户组成了帐户库，帐户具有帐户类型、帐户号、余额三个属性。

许多银行储户组成了储户库。

ATM系统包含了许多ATM机。

银行储户及ATM机两个类包含哪些属性，哪些操作，它们的可见性及操作的返回类型、参数个数、参数类型从类图上都一目了然。

通过类图不仅可以使设计者明确的表达自己的设计意图，也能帮助自己整理思路，充实及优化自己的设计。

3 序列图：显示具体用例（或者是用例的一部分）的详细流程。

它几乎是自描述的，并且显示了流程中中不同对象之间的调用关系，同时还可以很详细地显示对不同对象的不同调用。

序列图有两个维度：垂直维度以发生的时间顺序显示消息/调用的序列；水平维度显示消息被发送到的对象实例。

本例以时间为顺序描述了顾客在ATM机上取款时信息的流动情况，顺序图着重于对象间消息传递的时间顺序。

4 状态图：表示某个类所处的不同状态和该类的状态转换信息。

包括5个基本元素：初始起点，它使用实心圆来绘制；状态之间的转换，它使用具有开箭头的线段来绘制；状态，它使用圆角矩形来绘制；判断点，它使用空心圆来绘制；以及一个或者多个终止点，它们使用内部包含实心圆的圆来绘制。

本例描述了顾客在ATM机上进行操作会经历的几种状态，及各种状态之间转换的条件。
