Flatten objects and arrays展平对象和阵列

Get your fields on the same parent level, then move and embed them as needed..在同一父级上获取字段，然后根据需要移动和嵌入它们。

Target collections目标集合

Extract fields to a different target collection将字段提取到其他目标集合

Why use Reschema?为什么要使用重置架构？

With a powerful MongoDB migration tool, a schema makeover is only a few clicks away使用强大的MongoDB迁移工具，只需点击几下就可以完成模式改造

Clean up SQL migrations清理SQL迁移

Merge multiple sources easily轻松合并多个源

Reschema lets you merge data from multiple collections into one source collection, so you can start with the data you need without having to write a single $lookup.Reschema允许您将多个集合中的数据合并到一个源集合中，这样您就可以从需要的数据开始，而无需编写单个$lookup。

Update schema – minus the migration scripts更新模式-减去迁移脚本

MongoDB is great for ad-hoc schema changes, but these could get unruly over time. MongoDB非常适合临时模式更改，但随着时间的推移，这些更改可能会变得难以控制。With Reschema, you can easily restructure collections to reflect changes in your data. 使用Reschema，您可以轻松地重组集合，以反映数据中的更改。Like pressing a handy reset button.比如按下一个方便的重置按钮。

Improve performance by skipping unnecessary schema or document versions通过跳过不必要的架构或文档版本来提高性能

MongoDB lets you keep multiple versions of your schema or document, but this means duplicating indexes. MongoDB允许您保留模式或文档的多个版本，但这意味着要复制索引。Keep collections light and simple with a schema cleanup instead.相反，通过模式清理来保持集合的轻巧和简单。
