Question

我希望用户可以创建产品类别，如果它有SubCategory.define SubCategory.then定义该类别（或子类别）的表（品牌，组和字段）中的列。最后用户可以添加基于该品牌，组和之前定义的字段列。我想创建动态产品数据库，这是我第一次创建动态表。我只是担心

1-Correct Creation

2性能问题（毫无疑问是关于类型）。

我添加了我的图表和表脚本

Answer 1

如果这是你第一次，那就简单一点不要使用动态SQL来创建对象。

在进行设计之前，请查看众所周知的AdventureWorks数据库。它有类似的结构，你可以在这里得到一些想法： http://msftdbprodsamples.codeplex.com/releases

如果AdventureWorks不能满足您的要求，请提出有关如何根据业务需求对其进行修改的问题。

Answer 2

我找到答案：这是我希望通过一些更改进行设计的数据库表：

designing database to hold different metadata information
