我有这个 JSON 结构，需要将其传递到数据库。但我不知道我所做的结构是否是最好的，代码有一些重复，我认为这是不正确的，我认为这是没有必要的。
JSON:

我对 SQL 不太了解，所以我使用了在线转换，它返回了我这个:

这真的是数据库的最佳结构吗？这些值中的重复例如 ('Sandra Bullock', 162, 'sandra-bullock', 264, '1991-10-08 00:00:00', '2018-08-16 00:00:00 ')没有这个怎么优化？
最佳答案
答案取决于您想要实现的目标。此外，了解您将如何进一步使用这些数据也很重要。
- 结构不是很好。对于唯一的 JSON 项目，您将拥有多个记录(它们的数量可能很大 - 取决于 JSON)。我不确定以这种方式检索数据是否方便。 优先使用 relational model :
Generally, each table/relation represents one "entity type" (such as customer or product). The rows represent instances of that type of entity (such as "Lee" or "chair") and the columns representing values attributed to that instance (such as address or price).
所以，在你的情况下，我会使用多个表。
-- 视频，包含 {id、titulo、desc 等列}
-- carreira 将相关“atriz”记录的 id 作为单独的列和其他列 {id, inicio, Final}
-- carreira_videos - 存储 carreira-video 关系的单独表。 rable 可能仅包含两列:carreira_id 和 video_id。例如，示例 JSON 中的“Sandra Bullock”项目有带有两个视频的 carreira - 因此，在 carreira_videos 表中您将有两条记录:
carreira_id | video_id
264 | 264 2930500
264 | 264 2930499
-- atrizs 包含 {atriz, atriz-id, atriz-slug} 列和与 carreira_id 相关的单独列。
实际上，您的示例中存在大量数据重复，这是正确的。如果您的 JSON 在“info”节点中包含不止两个项目，那么就会有更多的数据重复项。如果您将使用关系模型(因为它在基于 SQL 的数据库中是首选)和如上所述的最佳模式，您将避免重复。
在进一步学习之前，您需要学习关系数据库和 SQL 的基础知识。如果您不理解它们，那么创建优化设计就不是真正的。

一切都取决于您的目标。
