结合课本内 容后得出的对于一个基本的餐馆订餐系统的需求和功能分析 其主要目的是为 系统的设计开发提供前期的准备工作 本系统的主要读者可以分为两部分 本系统的主要用户 用以做需求确 认 开发人员 开发小组的人员 用于概要设计和测试的依据 1 2 背景背景 本系统为一个餐馆的定餐系统 主要提供记录订餐和提醒的功能 1 3 定义定义 系统中所有以 JE 开头的类和变量均为 Just Enjoy 我们小组名称 的缩写 也用以和系统或者其他人开发的变量和函数相区别 1 4 参考资料参考资料 系统分析设计 美 John W Satzinger SQL Server 开发精髓 美 Rober B Jackson 软件工程 第二版 张海潘 面向对象设计 UML 实践 英 Mark Priestley 2 任务概述任务概述 2 1 目标目标 本系统是一个餐馆订餐系统 主要功能是为餐馆提供订餐记录和维护功能 3 同时由我们自己扩展了订菜和定时提醒的功能 下面使用了用例图的方式表现 了整个系统的所有功能 系统用例图如图 1 1 所示 Display bookings Staff Cancel booking M Record booking M Remind booking M Receptionist M Record arrival M Record walk
