CRUD Operations操作¶

CRUD (Create, Read, Update, Delete) operations allow you to work with the data stored in MongoDB.CRUD（创建、读取、更新、删除）操作允许您处理存储在MongoDB中的数据。

The CRUD operation documentation is categorized in two sections:CRUD操作文件分为两部分：

• Read Operations读取操作 find and return documents stored within your MongoDB database.查找并返回存储在MongoDB数据库中的文档。
• Write Operations写操作 insert, modify, or delete documents in your MongoDB database.在MongoDB数据库中插入、修改或删除文档。

Some operations combine aspects of read and write operations. 有些操作结合了读写操作的各个方面。See our guide on compound operations to learn more about these hybrid methods.有关这些混合方法的更多信息，请参阅我们的复合操作指南。
