电商平台商品模块数据库设计

一个完善的电商商品数据库设计需要考虑商品基本信息、分类体系、库存管理、价格体系、营销属性等多个方面。以下是电商平台商品模块的核心数据库表设计。

核心表结构

1. 商品基础表 (products)

CREATE TABLE products (product_id BIGINT PRIMARY KEY AUTO_INCREMENT,product_code VARCHAR(50) UNIQUE NOT NULL,product_name VARCHAR(100) NOT NULL,short_description VARCHAR(255),full_description TEXT,brand_id BIGINT,category_id BIGINT NOT NULL,supplier_id BIGINT,tax_class_id INT,weight DECIMAL(10,2),length DECIMAL(10,2),width DECIMAL(10,2),height DECIMAL(10,2),is_active BOOLEAN DEFAULT TRUE,is_featured BOOLEAN DEFAULT FALSE,is_bestseller BOOLEAN DEFAULT FALSE,is_new BOOLEAN DEFAULT TRUE,created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,FOREIGN KEY (brand_id) REFERENCES brands(brand_id),FOREIGN KEY (category_id) REFERENCES categories(category_id),FOREIGN KEY (supplier_id) REFERENCES suppliers(supplier_id)
);

2. 商品分类表 (categories)

CREATE TABLE categories (category_id BIGINT PRIMARY KEY AUTO_INCREMENT,parent_id BIGINT,category_name VARCHAR(50) NOT NULL,description TEXT,image_url VARCHAR(255),sort_order INT DEFAULT 0,is_active BOOLEAN DEFAULT TRUE,created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,FOREIGN KEY (parent_id) REFERENCES categories(category_id)
);

3. 品牌表 (brands)

CREATE TABLE brands (brand_id BIGINT PRIMARY KEY AUTO_INCREMENT,brand_name VARCHAR(50) NOT NULL,brand_logo VARCHAR(255),description TEXT,is_featured BOOLEAN DEFAULT FALSE,sort_order INT DEFAULT 0,created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

4. 商品属性表 (product_attributes)

CREATE TABLE product_attributes (attribute_id BIGINT PRIMARY KEY AUTO_INCREMENT,attribute_name VARCHAR(50) NOT NULL,attribute_code VARCHAR(50) UNIQUE NOT NULL,attribute_type ENUM('text', 'select', 'multiselect', 'boolean', 'date', 'decimal') NOT NULL,is_filterable BOOLEAN DEFAULT FALSE,is_visible BOOLEAN DEFAULT TRUE,is_required BOOLEAN DEFAULT FALSE,sort_order INT DEFAULT 0
);
