关于数据交换

数据交换提供了一个数据中心，可用于与您邀请的选定成员组安全地进行数据协作。作为提供商，您可以借助它发布数据，然后参与交换的使用者就可以发现这些数据。

With a Data Exchange, you can easily provide data to a specific group of consistent business partners taking part in the Data Exchange, such as internal departments in your company or vendors, suppliers, and partners external to your company. If you want to share data with a variety of consumers inside and outside your organization, you can also use listings offered to specific consumers or publicly on the Snowflake Marketplace.

Company A also publishes a listing to the data exchange which is then accessed by Company B in a separate organization, also participating in the data exchange. Company B shares a listing which is then accessed by your account. Each company account is creating a listing from a share, which is in turn created from a database in their account.

You can manage membership, access to data, and audit data usage, as well as apply security controls to the data shared in the Data Exchange. See Manage data listings.
