一、需求分析
随着餐饮行业的迅速发展，现有的人工管理方式已经不能呢个满足管理者的需求，广大餐饮业经营者已经意识到使用计算机应用软件的重要性，决定在餐饮
企业的经营管理上引入计算机应用软件管理系统。
酒店管理系统的大致功能：
1． 开台点餐 2． 菜品管理 3． 自动结账
4． 后台菜系菜品管理 5． 日月年结账报表 6． 用户设置
根据需求分析，本系统采用的语言：
（1）本系统采用Java语言，Java是目前使用最为广泛的计算机语言之一。它具有简单，面向对象，稳定，与平台无关等特点。说他简单，并不是说这门语言很干瘪，而是一种清楚更容易理解的方式实现程序。面向对象是基于对象的变成更符合人的思维方式，使人们更容易编写程序。
（2）本系统还采用SQL语言，SQL Server具有许多显着优点：易用性、适合分布组织的可伸缩性、用于决策支持的数据仓库功能、与许多其他服务器软件紧密关联的集成性、良好的性价比等。
（3） 本系统有效的利用Java和SQL的优点。
二、系统运行环境
操作系统为Windows 7、windows XP或windows 2003 使用的集成开发工具Eclipse 数据库采用SQL Server2008，项目运行环境为JDK 7。
三、功能需求描述
1．开台签单工作区的功能：主要功能有开台、点菜、加菜、签单、查看开台信息和签单信息。
2．自动结账工作区的功能：一个功能是自动计算当前选中餐台的消费金额；另一个功能是在结账时自动计算找零金额。
3．结账报表工作区功能：日结帐报表，月结账报表，年结账报表。 4．后天管理工作区功能：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
酒店管理系统的需求包括开台点菜功能、智能化获取菜品功能、自动结账功能、营业额报表功能等。在这些功能总主要涉及的数据表包括台号表、菜品表、消费单表；为了使系统更加的完善，还需要为菜品分类，即需要用到菜系表；为了实现菜品的日销售情况统计，还要建立一个消费项目表，用来记录消费单消费的菜品。
5．2数据库概念设计
数据库设计是系统设计过程中的重要组成部分，它是通过管理系统的整天需求而制定的，数据库设计的好坏直接影响到系统的后期开发。
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
