How to design an efficient MySQL table structure to implement the video playback function?

With the improvement of network bandwidth and the increase in user demand for high-quality videos, video playback functions are becoming more and more common in various websites and applications. In order to achieve efficient video playback function, it is crucial to design a reasonable MySQL table structure. This article will introduce how to design an efficient MySQL table structure to support the video playback function and provide specific code examples.

1. Design the video information table

First, we need to design a video information table to store the basic information of the video. This table can contain the following fields:

video_id: video ID, as the primary key
title: video title
description: video description
url: video address
duration: video duration
size: video size
create_time: video upload time

Sample code:

CREATE TABLE video_info (
video_id INT(11) PRIMARY KEY,
title VARCHAR(255 ),
description TEXT,
url VARCHAR(255),
duration INT(11),
size INT(11),
create_time DATETIME
);

2. Design the video tag table

In order to provide better video recommendation and classification functions, we can design a video tag table to store the tag information of the video. This table can contain the following fields:

tag_id: Tag ID, as primary key
tag_name: Tag name

Sample code:

CREATE TABLE video_tag (
tag_id INT(11) PRIMARY KEY,
tag_name VARCHAR(255)
);

3. Design the video tag association table

In order to realize the many-to-many relationship between videos and tags, We can design a video tag association table to store the association between videos and tags. This table can contain the following fields:

video_id: video ID, as a foreign key to the video information table
tag_id: tag ID, as a foreign key to the video tag table

Sample code ：

CREATE TABLE video_tag_relation (
video_id INT(11),
tag_id INT(11),
FOREIGN KEY (video_id) REFERENCES video_info(video_id),
FOREIGN KEY (tag_id ) REFERENCES video_tag(tag_id),
PRIMARY KEY (video_id, tag_id)
);

4. Design the video playback history table

In order to record the user’s video viewing history, we You can design a video playback history table to store information about videos watched by users. This table can contain the following fields:

user_id: user ID, associated to the user information table as a foreign key
video_id: video ID, associated to the video information table as a foreign key
watch_time: watch time

Sample code:

CREATE TABLE video_play_history (
user_id INT(11),
video_id INT(11),
watch_time DATETIME,
FOREIGN KEY (user_id) REFERENCES user_info(user_id),
FOREIGN KEY (video_id) REFERENCES video_info(video_id),
PRIMARY KEY (user_id, video_id)
);

Through the above design, we can achieve an efficient MySQL table structure to support video playback function. Each table has reasonable fields to store relevant information, and the association between tables is achieved through foreign key associations. By optimizing the use of query statements and indexes, database performance can be further improved.

Summary:

Through the MySQL table structure design introduced in this article, we can implement an efficient video playback function. Reasonable table structure and index design can improve query efficiency, and optimization based on specific needs can further improve database performance. Of course, in actual applications, more details and business needs need to be considered, and flexible adjustments and optimizations need to be made. Hope this article is helpful to you!
