How to design an efficient MySQL table structure to implement the advertising display function?

For the advertising display function, an efficient MySQL table structure design can improve the performance of query and insertion operations, and improve the stability and response speed of the system. The following will introduce in detail how to design an efficient MySQL table structure to implement the advertising display function, and provide corresponding code examples.

1. Advertising table design

1. Create advertising table Ads:

CREATE TABLE Ads (

id INT PRIMARY KEY AUTO_INCREMENT,
title VARCHAR(255) NOT NULL,
content TEXT NOT NULL,
image_url VARCHAR(255) NOT NULL,
link_url VARCHAR(255) NOT NULL,
display_count INT NOT NULL DEFAULT 0,
created_at DATETIME NOT NULL,
updated_at DATETIME NOT NULL

);

2. Add index: In order to improve query efficiency, you can add indexes to some commonly used fields:

ALTER TABLE Ads ADD INDEX idx_display_count (display_count);
ALTER TABLE Ads ADD INDEX idx_created_at (created_at);

2. Implementation of advertising function

1. Advertising function implementation steps:

• Query the advertisements that currently need to be displayed : Choose the right ad based on delivery schedule, ad priority, and number of impressions.

SELECT * FROM Ads
WHERE created_at < NOW()
AND display_count < max_display_count
ORDER BY priority DESC
LIMIT 1;

• Update the number of ad impressions: After each ad impression, update the number of ad impressions.

UPDATE Ads
SET display_count = display_count 1
WHERE id = {ad_id};

2. Code example:

// Query the ads that currently need to be displayed
function getAds() {

$query = "SELECT * FROM Ads 
          WHERE created_at < NOW() 
          AND display_count < max_display_count 
          ORDER BY priority DESC 
          LIMIT 1";
// 执行查询...
// 返回查询结果

}

// Update the number of ad impressions
function updateAdDisplayCount($ adId) {

$query = "UPDATE Ads 
          SET display_count = display_count + 1 
          WHERE id = {$adId}";
// 执行更新...
// 返回更新结果

}

//Sample call
$ad = getAds(); // Get the ads that need to be displayed currently
if ($ad) {

// 展示广告...
updateAdDisplayCount($ad['id']);  // 更新广告展示次数

}
?>

3. Implement other functions

1. Advertising review function: Add a "status" field to the advertising table to indicate The review status of the ad, for example, 0 means not reviewed, 1 means reviewed.
2. Ad expiration function: Add an "expiration_date" field to the advertisement table to indicate the expiration time of the advertisement. When querying the advertisement, it is necessary to determine whether the advertisement has expired.
3. Advertisement deletion function: Add a "deleted" field to mark whether the advertisement has been deleted to avoid physical deletion of data and facilitate data recovery and management.
4. Advertising click rate statistics function: You can add a "click_count" field in the advertising table to record the number of clicks on the advertisement. Each time the advertisement is clicked, the number of clicks is updated.

Summary:

An efficient MySQL table structure is crucial to realizing the advertising display function. By properly designing the table structure, creating indexes, and optimizing the implementation of query and update operations, the performance and response speed of the ad display function can be improved. When implementing advertising functions, other functions can also be added according to specific needs, such as ad review, expiration and deletion functions, and ad click-through rate statistics functions. The implementation of these functions can further improve the efficiency and stability of the system.
