我正在建立一个电子商务网站，并决定尝试使用MongoDB。我的目标是实现充分的灵活性，最终，我不会受限于销售特定产品，受制于最初组合系统的限制。
因此，灵活性的目标，我必须能够基于属性创建产品。 FX。颜色，制造，速度等。所有属性必须是可选的。用户可以创建新属性，有些是默认系统属性（不可删除）。根据属性的配置，它将与“基础”或可配置产品分层。
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在简化方面得到改进？我害怕我要么过度或者做不到什么，因为我通过使用关系数据库发现我的想法“受损”。
祝你好运

我认为您的设计可以正常工作，但我认为不需要将必需属性和可选属性分隔为单独的子文档。
我不了解PHP，但是当您展示时将每种颜色视为单独的产品时，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“溢出”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只检查文档中是否存在可选值，并根据该值做出渲染或业务逻辑决策。 MongoDB的优势在于其灵活性。并非所有文件都必须相同。应编写应用程序代码以处理没有所有可能字段的文档。
