Abstract

Claims (61)

1 . A method performed by executing instructions on at least one hardware processor, the method comprising:

causing enablement of a consumer database account to use a query template based on a received preapproval of the query template, the query template including one or more blanks or placeholders, the query template configured to enable values to be entered into the one or more blanks or the one or more placeholders and to be used to execute a query based on the entered values;

receiving a query generated by the consumer database account, the query including the query template with entered values into the one or more blanks or the one or more placeholders of the query template;

determining particular source provider data for responding to the query based on entered values in the query template;

assessing whether the particular source provider data for the query meets one or more data restrictions of visibility of a defined access clean room;

validating that the query is consistent with the query template based on the assessment that the particular source provider data meets the one or more data restrictions of visibility for the defined access clean room; and

in response to validating that the query is consistent with the query template:

generating, based on validating that the query is consistent with the query template, query results by executing the query; and

transmitting at least a portion of the query results to the consumer database account.

2 . The method of claim 1 , further comprising:

generating, at a provider database account, an installation file that, when processed, generates instances of the defined access clean room providing clean room functionality, defines parameters for the instances of the defined access clean room, generates one or more procedures for the instances of the defined access clean room, and controls visibility of objects across different consumer accounts;

providing the installation file to the consumer database account; and

installing, in the consumer database account, the installation file to generate an application instance of the defined access clean room.

3 . The method of claim 2 , wherein both the provider database account and the consumer database account reside in a distributed database.

4 . The method of claim 2 , wherein:

the provider database account resides in a first networked database platform; and

the consumer database account resides in a second networked database platform.

5 . The method of claim 4 , wherein the first networked database platform and the second networked database platform are in different geographic regions.

6 . The method of claim 2 , wherein the installing of the application instance in the consumer database account comprises executing an installer script that includes commands for installing one or more database objects in the consumer database account.

7 . The method of claim 2 , wherein the query is directed to a combination of source provider data shared by the provider database account and source consumer data shared by the consumer database account with the application instance.

8 . The method of claim 7 , wherein the query performs an overlap analysis of the shared source provider data and the shared source consumer data.

9 . The method of claim 8 , wherein the overlap analysis is with respect to a user- identifier column in both the shared source provider data and the shared source consumer data.

10 . The method of claim 2 , further comprising sharing, by the provider database account, source provider data within a defined access clean room, the sharing making the source provider data accessible to the consumer database account via the application instance.

11 . The method of claim 1 , further comprising:

sharing, by a provider database account, the query template with the consumer database account via an application instance; and

receiving preapproval of the query template by the consumer database account.

12 . The method of claim 10 , further comprising assessing whether the query meets data restrictions of visibility to the source provider data that is shared with the defined access clean room.

13 . The method of claim 1 , further comprising:

receiving a second query generated by the consumer database account based on the query template;

determining that the second query is not consistent with the query template; and

rejecting the second query based on determining that the second query is not consistent with the query template.

14 . The method of claim 1 , wherein generating the query results comprises injecting noise data into the query results to implement differential privacy, wherein an amount of the noise data injected is based on an epsilon value indicative of a privacy budget.

15 . A computer system comprising:

at least one hardware processor; and

one or more non-transitory computer readable storage media containing instructions that, when executed by the at least one hardware processor, cause the computer system to perform operations comprising:

causing enablement of a consumer database account to use a query template based on a received preapproval of the query template, the query template including one or more blanks or placeholders, the query template configured to enable values to be entered into the one or more blanks or the one or more placeholders and to be used to execute a query based on the entered values;

receiving a query generated by the consumer database account, the query including the query template with entered values into the one or more blanks or the one or more placeholders of the query template;

determining particular source provider data for responding to the query based on entered values in the query template;

assessing whether the particular source provider data for the query meets one or more data restrictions of visibility of a defined access clean room;

validating that the query is consistent with the query template based on the assessment that the particular source provider data meets the one or more data restrictions of visibility for the defined access clean room; and

in response to validating that the query is consistent with the query template:

generating, based on validating that the query is consistent with the query template, query results by executing the query; and

transmitting at least a portion of the query results to the consumer database account.

16 . The computer system of claim 15 , wherein the operations further comprise:

generating, at a provider database account, an installation file that, when processed, generates instances of the defined access clean room providing clean room functionality, defines parameters for the instances of the defined access clean room, generates one or more procedures for the instances of the defined access clean room, and controls visibility of objects across different consumer accounts;

providing the installation file to the consumer database account; and

installing, in the consumer database account, the installation file to generate an application instance of the defined access clean room.

17 . The computer system of claim 16 , wherein both the provider database account and the consumer database account reside in a distributed database.

18 . The computer system of claim 16 , wherein:

the provider database account resides in a first networked database platform; and

the consumer database account resides in a second networked database platform.

19 . The computer system of claim 18 , wherein the first networked database platform and the second networked database platform are in different geographic regions.

20 . One or more non-transitory computer readable storage media containing instructions that, when executed by at least one hardware processor of a computer system, cause the computer system to perform operations comprising:

causing enablement of a consumer database account to use a query template based on a received preapproval of the query template, the query template including one or more blanks or placeholders, the query template configured to enable values to be entered into the one or more blanks or the one or more placeholders and to be used to execute a query based on the entered values;

receiving a query generated by the consumer database account, the query including the query template with entered values into the one or more blanks or the one or more placeholders of the query template;

determining particular source provider data for responding to the query based on entered values in the query template;

assessing whether the particular source provider data for the query meets one or more data restrictions of visibility of a defined access clean room;

validating that the query is consistent with the query template based on the assessment that the particular source provider data meets the one or more data restrictions of visibility for the defined access clean room; and

in response to validating that the query is consistent with the query template:

generating, based on validating that the query is consistent with the query template, query results by executing the query; and

transmitting at least a portion of the query results to the consumer database account.
