A successful e-commerce platform is inseparable from a reasonable and maintainable database table structure to support its functions and business processes. In this article, we will introduce in detail how to design a maintainable MySQL table structure to implement e-commerce functions, and provide detailed code examples.

  1. User table design

The user table is one of the most basic tables in the e-commerce platform, used to store basic information of users. The following is an example of a user table:

CREATE TABLE users (
  id INT PRIMARY KEY AUTO_INCREMENT,
  username VARCHAR(50) NOT NULL,
  email VARCHAR(100) NOT NULL,
  password VARCHAR(100) NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
  1. Product table design

The product table is used to store product information on the e-commerce platform. The following is an example of a product table:

CREATE TABLE products (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(100) NOT NULL,
  price DECIMAL(10, 2) NOT NULL,
  description TEXT,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
  1. Order table design

The order table is used to store user purchase records and order information. The following is an example of an order table:

CREATE TABLE orders (
  id INT PRIMARY KEY AUTO_INCREMENT,
  user_id INT NOT NULL,
  product_id INT NOT NULL,
  quantity INT NOT NULL,
  total_price DECIMAL(10, 2) NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (user_id) REFERENCES users(id),
  FOREIGN KEY (product_id) REFERENCES products(id)
);
  1. Shopping cart table design

The shopping cart table is used to store the user's shopping cart information, making it easy for users to view and manage shopping at any time Goods in the car. The following is an example of a shopping cart table:

  product_id INT NOT NULL,
  quantity INT NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (user_id) REFERENCES users(id),
  FOREIGN KEY (product_id) REFERENCES products(id)
);
  1. Address table design

The address table is used to store the user's delivery address information to facilitate the user to select the appropriate one when placing an order. the address of. The following is an example of an address table:

CREATE TABLE addresses (
  id INT PRIMARY KEY AUTO_INCREMENT,
  user_id INT NOT NULL,
  name VARCHAR(50) NOT NULL,
  street VARCHAR(100) NOT NULL,
  city VARCHAR(50) NOT NULL,
  state VARCHAR(50) NOT NULL,
  zip_code VARCHAR(20) NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (user_id) REFERENCES users(id)
);

Through the above example, we can see that a maintainable MySQL table structure should:

  • Reasonably design the association between tables Relationships, use foreign keys to establish reference relationships;
  • Use appropriate data types to store different types of data;
  • Add necessary constraints and default values ​​to ensure data integrity and Consistency;
  • Use good naming conventions to improve code readability and maintainability.

I hope the examples provided in this article can help you design a maintainable MySQL table structure to implement e-commerce functions. Of course, depending on specific business needs, you may need to adjust the table structure design according to the actual scenario.
