MySQL implements the marketing activity management function of the food ordering system, which requires specific code examples
With the development of the Internet and mobile technology, the food ordering system has become an important part of the catering industry. An important tool to facilitate online ordering and automate order processing. In order to further enhance user experience and increase sales, catering companies usually use various marketing activities to attract customers. This article will introduce how to use the MySQL database to implement the marketing activity management function of the ordering system, and provide some specific code examples.
In the ordering system, the marketing activity management function mainly includes the following aspects: entry and display of activity information, activation and disabling of activities, association of activities and dishes, and generation and use of coupons. Let’s introduce them one by one below.
First, we need to create a table named "activities" to store activity information. The table contains fields: activity ID, activity name, activity start time, activity end time, activity description, and activity status. Among them, the activity status is used to identify the validity of the activity, 1 means enabled, 0 means disabled.
CREATE TABLE activities ( id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(255) NOT NULL, start_time DATETIME NOT NULL, end_time DATETIME NOT NULL, description TEXT, status TINYINT DEFAULT 1 );
Next, we create a table named "activity_dishes" to store the relationship between activities and dishes. The table contains fields: association ID, activity ID and dish ID.
CREATE TABLE activity_dishes ( id INT PRIMARY KEY AUTO_INCREMENT, activity_id INT NOT NULL, dish_id INT NOT NULL, FOREIGN KEY (activity_id) REFERENCES activities(id), FOREIGN KEY (dish_id) REFERENCES dishes(id) );
At the same time, we also need to create a table named "coupons" to store coupon information. The table contains fields: coupon ID, coupon code, coupon type, discount amount, and coupon status. Among them, the coupon status is used to identify the usage of the coupon, 0 means not used, and 1 means used.
CREATE TABLE coupons ( id INT PRIMARY KEY AUTO_INCREMENT, coupon_code VARCHAR(255) NOT NULL, coupon_type VARCHAR(50) NOT NULL, discount FLOAT NOT NULL, status TINYINT DEFAULT 0 );
Now that we have created the necessary table structure, let's implement the marketing activity management function of the ordering system through specific code examples.
First, we can add an activity record to the "activities" table through the following code:
INSERT INTO activities (name, start_time, end_time, description) VALUES ('新用户专享活动', '2022-01-01 00:00:00', '2022-01-31 23:59:59', '仅限新用户使用,享受8折优惠');
Then, we can associate a dish with the above activity through the following code:
INSERT INTO activity_dishes (activity_id, dish_id) VALUES (1, 101);
Next, we can generate a coupon through the following code:
INSERT INTO coupons (coupon_code, coupon_type, discount) VALUES ('ABC123', '折扣券', 0.8);
In order to use the coupon, we can update the status field in the "coupons" table through the following code:
UPDATE coupons SET status = 1 WHERE coupon_code = 'ABC123';
Through the above code examples, we can implement the marketing activity management function of the ordering system. When a user participates in a designated activity and associates it with a dish, the system will automatically calculate the discount amount and generate a corresponding coupon. When a user places an order, the system will automatically determine whether the conditions for using the coupon are met, and if so, the coupon will be automatically applied.
To sum up, implementing the marketing activity management function of the ordering system through the MySQL database can help catering companies improve user experience and increase sales. This requires us to establish a suitable table structure and use SQL statements to enter and update data. Through the above code examples, we hope to provide some reference and help for practitioners in the catering industry.
