Snowflake 简明教程

Snowflake - Objects

Snowflake 在三个临时存储区内从逻辑上组织数据 − 帐户、数据库和模式。

Snowflake logically organizes data in three stages − Account, Database and Schema.

数据库和模式在 Snowflake 帐户内从逻辑上组织数据。一个帐户可以有多个数据库和模式，但一个数据库必须与一个模式相关联，反之亦然。

Database and Schemas organize data logically within a Snowflake Account. An Account can have multiple databases and schemas, but a database must be tied up with only one schema and vice versa.
