In the context of Snowflake's Secure Data Sharing, the account that creates a share object and makes its data available to other accounts is officially termed a "data provider." The provider maintains full ownership and control over the shared data, including granting and revoking access. The accounts that are granted access to the share and can query the data are known as "data consumers." This provider-consumer model is fundamental to how data is shared securely across different Snowflake accounts.

B. A data consumer is the account that receives or accesses the shared data, not the one that shares it.

C. "Data reader" is a descriptive term but not the official Snowflake terminology for an account in a sharing relationship.

D. A data administrator is a role within an account (e.g., ACCOUNTADMIN) responsible for management, not the term for the account itself in a sharing context.

- Snowflake Documentation. (n.d.). Introduction to Secure Data Sharing. In Secure Data Sharing. Retrieved from https://docs.snowflake.com/en/user-guide/data-sharing-intro. "With Secure Data Sharing, no actual data is copied or transferred between accounts. All sharing is accomplished through Snowflake’s unique services layer and metadata store. This is an important concept because it means that shared data does not take up any storage in a consumer account and, therefore, does not contribute to the consumer’s monthly data storage charges. The only charges to consumers are for the compute resources (i.e. virtual warehouses) used to query the shared data." The page further defines the roles of Provider and Consumer accounts.
