How to design the inventory table structure of the mall in MySQL?

When designing the inventory table structure of the mall, you need to consider the attributes, classification, inventory quantity, price and other information of the product. The following will introduce how to design the mall's inventory table structure in MySQL with specific code examples.

First, we can create a table named products to store the basic information of the product, including product ID, name, category, price, etc.:

CREATE TABLE products (
  id INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(100) NOT NULL,
  category VARCHAR(50) NOT NULL,
  price DECIMAL(10, 2) NOT NULL
);

Next , you can create a table named inventory to store product inventory information, including product ID, inventory quantity, etc.:

CREATE TABLE inventory (
  id INT AUTO_INCREMENT PRIMARY KEY,
  product_id INT NOT NULL,
  quantity INT NOT NULL,
  FOREIGN KEY (product_id) REFERENCES products(id)
);

In this table, the product_id column As a foreign key, it is associated with the id column of the products table, ensuring that the product ID in the inventory table corresponds to the ID in the product table.

In addition, when designing the inventory table structure, you can also consider some other attributes, such as product specifications, colors, etc. Corresponding columns can be added to the products table to store these attributes. For example, add a specification column to store product specification information:

ALTER TABLE products
ADD COLUMN specification VARCHAR(100);

In this way, we can The specification information of the product is obtained by querying the specification column in the products table.

If the product has multiple specifications and multiple attributes, you can consider using other related tables to store this information, and then associate it to the products table through foreign keys. Taking the color information of products as an example, you can create an association table named product_colors to store the relationship between products and colors:

CREATE TABLE product_colors (
  id INT AUTO_INCREMENT PRIMARY KEY,
  product_id INT NOT NULL,
  color VARCHAR(50) NOT NULL,
  FOREIGN KEY (product_id) REFERENCES products(id)
);

In this table, product_id# The ## column is associated with the id column of the products table as a foreign key, and the color column stores the color information of the product.
