Accessing listings in a data exchange

A system comprising:

• a memory;
• and
• a processor, operatively coupled to the memory, the processor to:
• create a first listing in a data exchange, the first listing referencing a first database of a plurality of databases and specifying identity-based sharing of the first database, wherein the identity-based sharing is configured to filter access to first data of the first database based on identity data associated with an access request to the first data;
• create a second listing in the data exchange associated with a provider and specify identity-based sharing of a second database of the plurality of databases, the second listing referencing the second database of the plurality of databases and data of the first database filtered according to the identity-based sharing of the first database as filtered based on the identity data associated with the provider;
• and
• receive an instruction from a user of the data exchange, the instruction referencing the second listing and instructing addition of the second listing to a set of consumed data shares accessible by the user.

A non-transitory computer-readable medium having instructions stored thereon which, when executed by a processor cause the processor to:

• create a first listing in a data exchange, the first listing referencing a first database of a plurality of databases and specifying identity-based sharing of the first database, wherein the identity-based sharing is configured to filter access to first data of the first database based on identity data associated with an access request to the first data;
• create, by the processor, a second listing in the data exchange associated with a provider and specify identity-based sharing of a second database of the plurality of databases, the second listing referencing the second database of the plurality of databases and data of the first database filtered according to the identity-based sharing of the first database as filtered based on the identity data associated with the provider;
• and
• receive an instruction from a user of the data exchange, the instruction referencing the second listing and instructing addition of the second listing to a set of consumed data shares accessible by the user.
