3、查询、修改、删除等维护性操作。餐饮管理系统有足够的存储容量，满足酒店每日营业的变动，另外，对于操作用户有一定的管理，并对用户的权限有一定的设置超级管理员拥有所有权限。经理除了系统维护外，其他操纵都可以，普通用户只能实现辅助工具的使用权限。1.1数据需求Tb_food-存储食品的Tb_foodtype-存储食品的类别Tb_Waiter-存储所有职员信息Tb_User-存储管理用户信息Tb_Room-存储餐厅桌台信息Tb_GuestFood-存储消费信息1.2总体设计餐饮管理系统辅助工具系统维护基础信息帮助系统设置退出添加用户锁定系统修改密码权限管理记事本计算器日历职员信息桌台信息退出系统关于结账
