目录一、需求分析 5二、系统运行环境 5三、功效需求描述 5四、模块结构图 6五、数据库设计 65．1数据库分析 65．2数据库概念设计 65．3数据库逻辑结构设计 7六、程序模块设计 8七、总结 36

一、需求分析伴随餐饮行业快速发展，现有人工管理方法已经不能呢个满足管理者需求，广大餐饮业经营者已经意识到使用计算机应用软件关键性，决定在餐饮企业经营管理上引入计算机应用软件管理系统。酒店管理系统大致功效：开台点餐菜品管理自动结账后台菜系菜品管理日月年结账报表用户设置依据需求分析，本系统采取语言：（1）本系统采取Java语言，Java是现在使用最为广泛计算机语言之一。它含有简单，面向对象，稳定，和平台无关等特点。说她简单，并不是说这门语言很干瘪，而是一个清楚更轻易了解方法实现程序。面向对象是基于对象变成更符合人思维方法，使大家更轻易编写程序。（2）本系统还采取SQL语言，SQLServer含有很多显著优点：易用性、适合分布组织可伸缩性、用于决议支持数据仓库功效、和很多其它服务器软件紧密关联集成性、良好性价比等。本系统有效利用Java和SQL优点。二、系统运行环境操作系统为Windows7、windowsXP或windows使用集成开发工具Eclipse数据库采取SQLServer，项目运行环境为JDK7。三、功效需求描述1．开台签单工作区功效：关键功效有开台、点菜、加菜、签单、查看开台信息和签单信息。2．自动结账工作区功效：一个功效是自动计算目前选中餐台消费金额；另一个功效是在结账时自动计算找零金额。3．结账报表工作区功效：日结帐报表，月结账报表，年结账报表。4．后天管理工作区功效：管理添加信息四、模块结构图模块结构图五、数据库设计5．1数据库分析酒店管理系统需求包含开台点菜功效、智能化获取菜品功效、自动结账功效、营业额报表功效等。在这些功效总关键包含数据表包含台号表、菜品表、消费单表；为了使系统愈加完善，还需要为菜品分类，即需要用到菜系表；为了实现菜品日销售情况统计，还要建立一个消费项目表，用来统计消费单消费菜品。5．2数据库概念设计数据库设计是系统设计过程中关键组成部分，它是经过管理系统整天需求而制订，数据库设计好坏直接影响到系统后期开发。5．3数据库逻辑结构设计台号表菜品表菜系表消费单表消费项目表管理员表六、程序模块设计功效模块整体设计：用户功效界面：代码：packagecom.mwq.frame;importjava.awt.BorderLayout;importjava.awt.Dimension;importjava.awt.GridBagConstraints;importjava.awt.GridBagLayout;importjava.awt.Insets;importjava.awt.event.ActionEvent;importjava.awt.event.ActionListener;importjava.awt.event.FocusEvent;importjava.awt.event.FocusListener;import.URL;importjava.util.Vector;importjavax.swing.BoxLayout;importjavax.swing.ImageIcon;importjavax.swing.JButton;importjavax.swing.JComboBox;importjavax.swing.JFrame;importjavax.swing.JLabel;importjavax.swing.JOptionPane;importjavax.swing.JPanel;importjavax.swing.JPasswordField;importcom.mwq.dao.Dao;importcom.mwq.mwing.MPanel;publicclassLandFrameextendsJFrame{ privateJPasswordFieldpasswordField;//密码框 privateJComboBoxusernameComboBox;//用户名下拉菜单 publicstaticvoidmain(Stringargs[]){ try{ LandFrameframe=newLandFrame();
