MySQL implements the evaluation management function of the ordering system

The ordering system is a common management tool in the modern catering industry. It can provide customers with convenient and fast services. Order service. The evaluation management function is a very important part of the ordering system. It can help restaurants understand customers' evaluations of the restaurant, thereby better improving service quality and increasing customer satisfaction.

This article will introduce how to use the MySQL database to implement the evaluation management function of the ordering system, and provide specific code examples.

First, create a table named "order" in the MySQL database to store the customer's order information. The fields of the table include order number (order_id), customer name (customer_name), dish name (dish_name), quantity (quantity), total price (total_price), etc.

CREATE TABLE `order` (
  `order_id` INT AUTO_INCREMENT PRIMARY KEY,
  `customer_name` VARCHAR(50) NOT NULL,
  `dish_name` VARCHAR(100) NOT NULL,
  `quantity` INT NOT NULL,
  `total_price` DECIMAL(10,2) NOT NULL
);

Next, create a table named "evaluation" in the database to store customer evaluation information. The fields of the table include evaluation number (evaluation_id), order number (order_id), evaluation content (content), score (score), etc.

CREATE TABLE `evaluation` (
  `evaluation_id` INT AUTO_INCREMENT PRIMARY KEY,
  `order_id` INT,
  `content` TEXT,
  `score` INT
);

Then, we can use the INSERT statement provided by the MySQL database to insert the customer's order information into the "order" table.

INSERT INTO `order` (`customer_name`, `dish_name`, `quantity`, `total_price`) 
VALUES ('张三', '宫保鸡丁', 2, 48.00);

After the customer orders food, we can use the INSERT statement to insert the customer's evaluation information into the "evaluation" table.

INSERT INTO `evaluation` (`order_id`, `content`, `score`) 
VALUES (1, '菜品口感不错，服务很周到。', 5);

Customers can evaluate the restaurant based on their actual experience. The evaluation content can be a text description, and the score can be set from 1 to 5 points.

In addition, we can also use the SELECT statement to query customer evaluation information from the "evaluation" table.

SELECT * FROM `evaluation` WHERE `order_id` = 1;

Through the above operations, we can realize the evaluation management function of the ordering system. Restaurants can improve the taste of dishes and service quality based on customer evaluation information to meet customer needs and improve customer satisfaction.

To summarize, this article introduces how to use the MySQL database to implement the evaluation management function of the ordering system, and provides specific code examples. Through the evaluation management function, restaurants can understand customer evaluations in real time, thereby improving services and increasing customer satisfaction. At the same time, this also provides restaurants with better business competitiveness.
