Schema更少的数据库表——实际妥协
原标题:Schema less SQL database table - practical compromise

这个问题是试图为找到一个实际解决办法。 问题

我需要为我的SQ数据库设计一个半奇马少。 然而,我可以限制灵活性,把它变成整个结构模式。 转向结构化程度较低的数据库可能是今后的一种选择,但现在,我 st着SQ。

我在一份库克数据库中有一个表格(请上)。 如果加上一行,它就必须能够储存大量“金属”的雷区。 举例来说,是否有能力提供诸如标签、合伙人等任意元数据。 所有领域都是任择的,但问题是它们具有不同类型。 有些可能是数字,有些可能是文字性的。

缩略语 等看来是直接的,尽管它在整个EAV模型中引述了这一最后回答,它相当浪费。 而且,我想象,在增长的时候,这个问题会非常缓慢。 不过,我并不指望以本表格中的任何内容搜寻或分类。 我完全需要的是,当我从<条码>中删除时。 Foo,这些额外属性也应获得。

在数据库中是否有实施这种设置的最佳做法,或者我只是错误地看待整个结构?

最佳回答

在您的表格“Foo”上添加一个“Metafields”栏,并作为XML或JSON星储存其元数据。
