Implementation method of table management function in ordering system developed with Go language

Go language development method to implement the table management function in the ordering system

1. Introduction
With the development of the catering industry and people's attention to catering services Demand continues to increase, and many restaurants are beginning to use ordering systems to improve work efficiency and customer experience. Among them, the table management function is an important part of the ordering system. It can help restaurants manage the status of tables, reservation information, customer flow, etc. This article will introduce how to use Go language to develop the table management function in the ordering system, and give specific code examples.

2. Table status management

1. Database design
   When developing a restaurant ordering system, we need to use a database to store table information and status. You can design a data table named "tables", which contains the following fields:
2. id: table ID, as the primary key
3. name: table name
4. status: Table status (for example: free, reserved, occupied, etc.)

5. Go code example

   // 定义桌台结构体
   type Table struct {
    ID     int
    Name   string
    Status string
   }
   
   // 获取所有桌台信息
   func getAllTables() ([]Table, error) {
    // 连接数据库获取桌台信息并返回
   }
   
   // 更新桌台状态
   func updateTableStatus(id int, status string) error {
    // 连接数据库更新桌台状态并返回
   }
   
   // 示例代码：获取所有桌台信息
   tables, err := getAllTables()
   if err != nil {
    // 错误处理
   } else {
    for _, table := range tables {
        fmt.Println(table.Name, table.Status)
    }
   }
   
   // 示例代码：更新桌台状态
   err := updateTableStatus(1, "已预定")
   if err != nil {
    // 错误处理
   }

3. Table reservation management

1. Database design
   In order to realize the table reservation function, we can design a data table named "reservations", which contains the following fields:
2. id: reservation ID, as the primary key
3. tableId: table ID, associated with the "tables" data table
4. customerName: customer name
5. reserveTime: reservation time
6. numPeople: number of diners
7. status: Reservation status (for example: accepted, pending, canceled, etc.)

8. Go code example

   // 定义预订结构体
   type Reservation struct {
    ID           int
    TableID      int
    CustomerName string
    ReserveTime  string
    NumPeople    int
    Status       string
   }
   
   // 获取所有预订信息
   func getAllReservations() ([]Reservation, error) {
    // 连接数据库获取预订信息并返回
   }
   
   // 添加预订信息
   func addReservation(tableID int, customerName string, reserveTime string, numPeople int) error {
    // 连接数据库添加预订信息并返回
   }
   
   // 更新预订状态
   func updateReservationStatus(id int, status string) error {
    // 连接数据库更新预订状态并返回
   }
   
   // 示例代码：获取所有预订信息
   reservations, err := getAllReservations()
   if err != nil {
    // 错误处理
   } else {
    for _, reservation := range reservations {
        fmt.Println(reservation.CustomerName, reservation.ReserveTime, reservation.NumPeople)
    }
   }
   
   // 示例代码：添加预订信息
   err := addReservation(1, "张三", "2021-01-01 18:00", 4)
   if err != nil {
    // 错误处理
   }
   
   // 示例代码：更新预订状态
   err := updateReservationStatus(1, "已取消")
   if err != nil {
    // 错误处理
   }

4. Table Traffic management
Table traffic management refers to real-time statistics and analysis of customer visit time, stay time and other indicators based on table usage, thereby providing better business decision support for the restaurant. You can use Go language to write scheduled tasks, regularly calculate and count data related to table traffic, and store the results in the database. The specific code examples involve a lot of content. You can refer to the sample codes given above for writing.

5. Summary
This article introduces the implementation method of using the Go language to develop the table management function in the ordering system, and gives corresponding code examples. In actual development, the code can be modified and improved according to specific needs. By rationally designing data tables and writing corresponding Go functions, functions such as table status management, table reservation management, and table flow management can be realized, providing efficient table management services for restaurants.
