工作台

需求分析和设计

工作台是系统运营的数据看板，并提供快捷操作入口，可以有效提高商家的工作效率。

工作台展示的数据：

•今日数据

•订单管理

•菜品总览

•套餐总览

•订单信息

名词解释：

• 营业额：已完成订单的总金额

• 有效订单：已完成订单的数量

• 订单完成率：有效订单数 / 总订单数 * 100%

• 平均客单价：营业额 / 有效订单数

• 新增用户：新增用户的数量

接口设计：

• 今日数据接口

• 订单管理接口

• 菜品总览接口

• 套餐总览接口

• 订单搜索（已完成）

• 各个状态的订单数量统计（已完成）

1、今日数据接口

今日数据的接口设计：

代码设计

1、admin/WorkSpaceController
