MongoDB电商产品文档设计

Question

我正在构建一个电子商务网站，并决定试用 MongoDB。我的目标是实现完全的灵 active ，这样到最后，我就不会受制于销售特定产品，而受到系统最初组合方式的限制。

因此，灵 active 的目标是，我必须能够根据属性创建产品。外汇。颜色、制造商、速度等。所有属性都必须是可选的。用户可以创建新的属性，有些是默认的系统属性(不可删除)。根据属性的配置，它将与“基础”产品或可配置产品分层。

• 在目录中，我想拆分具有颜色属性的产品，以便每种颜色作为单独的产品呈现。我可以使用我当前的文档设计通过 MongoDB 实现这一目标吗？
• 我得出的结论是，在从 MongoDB 中选择产品时，在展示之前，我必须“填满”我的文档，或者做大量的数据映射。我错了吗？
• 考虑到一些产品有选项(颜色、尺寸)而另一些没有，那么进行库存管理的最佳和最有效的方法是什么？

如我的示例所示，我在属性下存储了普通属性，在文档选项下可以找到“必需”属性。

我的产品文档能否以某种方式改进，使事情变得更容易？我担心我在某件事上做得过头或做得不够，因为我发现我的想法因使用关系数据库而“受损”。

Answer 1

我认为您的设计会很好，尽管我认为没有必要将必需属性和可选属性分离到单独的子文档中。

我不懂 PHP，但要在显示时将每种颜色视为单独的产品，您可以执行以下操作:

product = db.products.findOne({sku: "..."})
for color in product.colors:
    # render the product with the color

没有必要“填满”您的文档——我假设您的意思是为每个可能的属性存储空值？您的应用程序代码应该简单地检查文档中是否存在可选值，并据此做出呈现或业务逻辑决策。 MongoDB 的优势之一是它的灵 active 。并非所有文件都必须相同。您的应用程序代码应编写为处理不包含所有可能字段的文档。
