mysql - 电子商务网站的数据库模式设计

问题描述

我正在制作一个电子商务网站并使用 MySQL 来存储数据。

我在下面添加了架构图。请让我知道设计中可能存在的缺陷或可能出现的其他问题。

我正在设计的产品在其表面处理、尺寸方面有很大的变化，并具有其独特的特性。

这是我想要实现的目标：

产品 A 可以有 1 种或多种变体。（例如：1.AA（哑光饰面）、AB（木饰面）、AC（油饰面））。
每个变体可以有 0 个或多个尺寸，例如 30x40、40x60 等。（例如：AA 可以有 30x40 和 40x60）
每个产品都有其独特的属性。（例如：产品A可以有Thickness，产品B可以有Class）
产品的 SKU 和价格取决于其所有不同的尺寸、表面处理及其独特的属性。

对于我本可以使用 EAV 的独特属性，但采用了这种方法。

让我在这里解释一下表格：

Brands、Category 和 Collections正是他们所说的。
base_relation_table是上述 3 个表之间的关系，所有可能的组合。
产品（包含所有产品，例如：产品 A，产品 B）和base_relation_table的引用ID以了解它属于哪个组合。它还引用了包含其外观（石头、木纹等）的图案。
product_option_relation是唯一属性的关系（例如产品 A ID、厚度 ID）
option_table只包含名称（厚度、等级、印刷技术等）
option_value包含 option_tables 的所有值（例如：0.7、0.9、Professional、Beginners 等）
product_variant包含产品的所有变体（例如：AA、AB、AC、BA、BB 等）
颜色，光洁度是 1:n 与所有产品变体。（例如：AA 亚光红色，AB 亮白色）
维度包含与product_variant的 n:m 关系
variant_values是所有属性、所有变体和独特属性的组合。

正如我之前提到的 SKU 和价格随着其独特性和变化属性而变化，所以我在这里添加了它。因为在这里我得到了所有的组合。

这是架构代码：

SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0;
SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;
SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';

SET SQL_MODE=@OLD_SQL_MODE;

有什么我想念的吗？会是规模吗？设计好看吗？
