什么是文档数据存储？
Document data stores are represented in JSON, where each document is itself a complex data structure. Documents can contain nested structures of various data types, and users can query these structures, retrieving or updating the document, or portions of it, without locking down the database. Documents are stored and retrieved through a unique primary key. \r
文档数据存储以 JSON 形式表示，每个文档本身都是一个复杂的数据结构。 文档可包含各种数据类型的嵌套结构，用户可以查询这些结构，检索或更新整个或部分文档，而无需锁定数据库。 通过唯一主键存储和检索文档。
