How to design an scalable MySQL table structure to implement product management functions?

Product management is one of the core functions of many e-commerce websites and other online stores. In order to support the efficiency and scalability of this feature, it is crucial to design a suitable MySQL table structure. This article will introduce how to design an extensible MySQL table structure to implement product management functions, and provide specific code examples.

1. Product master table design

First of all, we need to design a product master table to store the basic information of the product, such as product name, price, inventory, etc. The following is an example product master table design:

CREATE TABLE `product` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `name` VARCHAR(100) NOT NULL,
  `price` DECIMAL(10, 2) NOT NULL,
  `stock` INT(11) NOT NULL,
  `created_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  `updated_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

This product master table contains basic information about the product, and sets the price and inventory fields to non-empty.

2. Product classification table design

In order to support product classification management, we can design a product classification table to store product classification information. The following is an example product classification table design:

CREATE TABLE `category` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `name` VARCHAR(100) NOT NULL,
  `parent_id` INT(11) DEFAULT NULL,
  PRIMARY KEY (`id`),
  FOREIGN KEY (`parent_id`) REFERENCES `category`(`id`) ON DELETE SET NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

This product classification table contains the name of the category and the optional upper-level category ID. By relating itself using foreign keys, we can achieve a hierarchical structure of categories.

3. Product attribute table design

In addition to basic product information, products may also have some additional attributes, such as color, size, weight, etc. In order to support the management of these additional attributes, we can design a product attribute table. The following is an example product attribute table design:

CREATE TABLE `product_attribute` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `product_id` INT(11) NOT NULL,
  `name` VARCHAR(100) NOT NULL,
  `value` VARCHAR(255) NOT NULL,
  PRIMARY KEY (`id`),
  FOREIGN KEY (`product_id`) REFERENCES `product`(`id`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

This product attribute table contains product ID, attribute name and attribute value. By using foreign keys to associate the main product table, we can achieve associated management of product attributes.

4. Product Picture Table Design

Products usually need to display some pictures, such as the main product image, product detail images, etc. In order to support the management of product images, we can design a product image table. The following is an example product image table design:

CREATE TABLE `product_image` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `product_id` INT(11) NOT NULL,
  `url` VARCHAR(255) NOT NULL,
  `is_default` TINYINT(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`),
  FOREIGN KEY (`product_id`) REFERENCES `product`(`id`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

This product image table contains the product ID, image URL and whether it is the default image. By using foreign keys to associate the main product table, we can achieve associated management of product images.

To sum up, by designing an scalable MySQL table structure, we can implement a powerful product management function. Through the design of the product master table, product classification table, product attribute table and product picture table, we can store and manage the basic information, classification information, attribute information and picture information of the product. Not only that, if we need to expand other functions, we only need to make appropriate modifications and extensions.

Note: The above code examples are for reference only, and may need to be adjusted and optimized according to specific needs in actual applications.

How does MySQL handle data replication?How does MySQL handle data replication?Apr 28, 2025 am 12:25 AM

MySQL processes data replication through three modes: asynchronous, semi-synchronous and group replication. 1) Asynchronous replication performance is high but data may be lost. 2) Semi-synchronous replication improves data security but increases latency. 3) Group replication supports multi-master replication and failover, suitable for high availability requirements.

How can you use the EXPLAIN statement to analyze query performance?How can you use the EXPLAIN statement to analyze query performance?Apr 28, 2025 am 12:24 AM

The EXPLAIN statement can be used to analyze and improve SQL query performance. 1. Execute the EXPLAIN statement to view the query plan. 2. Analyze the output results, pay attention to access type, index usage and JOIN order. 3. Create or adjust indexes based on the analysis results, optimize JOIN operations, and avoid full table scanning to improve query efficiency.

How do you back up and restore a MySQL database?How do you back up and restore a MySQL database?Apr 28, 2025 am 12:23 AM

Using mysqldump for logical backup and MySQLEnterpriseBackup for hot backup are effective ways to back up MySQL databases. 1. Use mysqldump to back up the database: mysqldump-uroot-pmydatabase>mydatabase_backup.sql. 2. Use MySQLEnterpriseBackup for hot backup: mysqlbackup--user=root-password=password--backup-dir=/path/to/backupbackup. When recovering, use the corresponding life

The main reasons for slow MySQL query include missing or improper use of indexes, query complexity, excessive data volume and insufficient hardware resources. Optimization suggestions include: 1. Create appropriate indexes; 2. Optimize query statements; 3. Use table partitioning technology; 4. Appropriately upgrade hardware.

What are views in MySQL?What are views in MySQL?Apr 28, 2025 am 12:04 AM

MySQL view is a virtual table based on SQL query results and does not store data. 1) Views simplify complex queries, 2) Enhance data security, and 3) Maintain data consistency. Views are stored queries in databases that can be used like tables, but data is generated dynamically.

What is MySQL partitioning?What is MySQL partitioning?Apr 27, 2025 am 12:23 AM

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.
